There are a few aspects possible in a chart that I think of as the "It hurts to be you" aspects. You do have some, but it is possible to rethink how they operate in your life, and to implement some positive steps.
Saturn square moon, moon conjunct Pluto. Saturn often shows where we feel inadequate and not good-enough. The moon rules your feelings. Particularly with it conjunct Pluto, you are apt to spend time in your subconscious. Rationally your life might be going fine, but emotionally you feel pulled down.
Sun square Chiron. Chiron is a little planetoid that shows us "where it hurts." These hurts don't heal, but if we stay open to them, they can confer a lot of wisdom and compassion for other people. The sun is your identity, or sense of self.
Venus square Neptune can give you lovely idealism and a beautiful imagination, but when ordinary reality isn't as good as you hoped, it can leave you feeling bitterly disappointed. This is reinforced by the "sudden change" nature of Uranus also squaring Venus.
Saturn also rules self-discipline. So think about how you might discipline (Saturn) your feelings (moon) when you get into dark (Pluto) moods. A few sessions with a counselor might help to develop some techniques that you could practice.
Have you ever had a mental health evaluation? Sometimes these overwhelming feelings have a physical cause, and you can't just think or discipline yourself out of them. You might ask your doctor for a referral to a mental health specialist, just to gain clarity.
One other thing that occurs to me, is that with your sun, Mercury, and Venus in Aries, you kind of need to be the Woman Warrior in your life. Many women are trained from an early age to be sweet and deferential, but part of you needs an outlet for your more assertive Aries energy. Have you got some way to express Aries, like a high impact sport? Mars rules Aries and athletics, so picking up some kind of water-based sport (like an Aqua-fit class if you're a non-swimmer) might do wonders for your Pisces Mars.
Otherwise, part of you will be living with that despair, of not being true to your out-of-the-box nature. If you are behaving like an Aries now, that is super. Just going out for a good run (or its equivalent, like a power walk or session at the gym) should be helpful.
