Of course it will change. Change is inherent to life.
It is a matter of recognizing your windows of opportunity and having a feeling and confidence of what to do with them, expecting there will be some setbacks and problems to overcome. That is the other thing inherent to life: challenges -- setbacks and problems to solve.
I don't agree with the above interpretation of Moon trine Saturn. It is an aspect of patience and discipline. It indicates constructive ability in learning the relational give-and-take with others and the balance of pleasure/gratification built up by constructive efforts. Just know you've got inherent wisdom of this sort that will become more apparent to you in time. To a degree it indicates a more sober, realistic emotional nature, but that will pay off for you with patience.
Some of the clues to your frustration may lie in seeing how Sun & Mercury form a square to Moon. This can indicate enthusiasm generated by ideas and talk around them that spring from your needs and desires, but which may not take into account the time factor, delays, etc, of Saturn. The Gemini often has a youthful perspective that is better informed of what to expect (or when to expect nothing in particular, but merely be expectant). In other words, don't depend on happiness in life by expecting your ideas of happiness to be fulfilled. Learn what it is by an ongoing communicative exchange with others and their experience and knowledge in life that can be added to yours.
I see a lot of potential for enjoyment in life for you just in being curious about others, about various ways of living, learning, stories to be told and heard. This is implied in the Moon square Sun-Mercury aspect. You've got the two luminary energies involved with Mercury, which is storyteller, student, listener, conversationalist, and even teacher.
In the next months (year or so) you'll have the transit of Jupiter pass over Asc/Pluto, squaring your natal Venus-Mars-Jupiter. That should provide an energy boost and some momentum to feel like you are moving forward. That will begin in the second half of November.
So understand it is a window of opportunity for energizing your life with decisions, even a change of direction. If you'd like a better job or even a more acceptable line of work now is the time to plan you strategy for that so you'll be ready when that transit series begins.
For now the strongest transit happening in your chart is Pluto [21S43] is conjunct and parallel natal Neptune [21S41]. This certainly can change your mood about the world and can affect your worldview. I strongly urge you to look to positive, informative, interesting reading material to start opening up the parts of life and the world that will spark broader understanding that could prove useful in how you live your life. It could spur realizations that will bring you to more meaningful ideals for living, a deeper belief about yourself and the essence of life. Your understanding and spiritual reference point is being transformed with this transit, but it is only what you make of it, as AppLeo mentioned. This transit can be a strong boost to creativity as well if you let yourself put it into action in whatever creative direction is immediately there for you -- even the smallest thing like drawing.
Pluto transits are all about different ways of feeling your own power. While this transit to Neptune will affect your moods and views, possibly ideals for living, what it can do with creativity is hard to estimate. Maybe you can even find your creativity for the first time.
All this stuff about creativity and life ideals is especially true since Neptune 12°Pisces is sextile your natal Pluto. So there is a strong theme of Neptune-Pluto right now. That is spiritual transformation, opening and deepening of perception. See if you can try simple creative tasks to shift how you feel about yourself and your life now, and something like hypnosis audios to get in touch with your subconscious. Often when life feels dull and boring because of external circumstances, it is because we are not tapping into the beautiful, rich, colorful, and powerful dimensions inside ourselves. Now is a good time to do that while these Neptune-Pluto transits are here.
Notice Neptune's position now has it quincunx/150° your natal Venus-Mars-Jupiter conjunction. This to me speaks of some essential shifts in your expectations and life guiding ideals, possibly allowing you a vision for your life (more reason to try something like guided meditations or hypnosis towards that end), but also whenever Neptune touches Venus and/or Mars we have activation of the imagination towards creative results. Try it and see what you get.
Uranus is now sextile your natal Sun (and Mercury off and on). So now is a good time to create opportunities for yourself by being more spontaneous. This is not a super strong transit so long as one (either Sun or Mercury) is being transited. So make more mental effort to put some waves into motion with others and your surroundings by choosing to be more spontaneous, take the long way home, change up your routine, spend time with different people, etc. Uranus brings great results when we are just willing to get out of our ruts and liver freer and more spontaneously.
Good luck. Stay in touch and let us know how things are going.
this year in April I got in my dreams some signs from the Angels that I'm on a good path in my life and that soon I will get my prize, but this hard time that is currently passing causes me to have doubts... I know that I shouldn't doubt them as they're a good beings, but some days make me powerless... I'm trying to do my best, but there are still some uncertainties and they stop me from acting... and actually I'm going through the next very challenging aspect - Neptune quincunx Jupiter, that checks faith in my plans... I'm really tired of this and I hope that soon there will be a time that will allow me to take a deep breath and relax...
