You will be having a transit of Saturn to your natal Moon. I can relate as I have Saturn transiting opposite my Moon. Its not as bad as all that, amongst other things, you may feel more serious than usual. Don't worry though, there are other transits that will brighten things up from time to time. The transit is ultimately for your good, it will help you grow as a person, and so move in directions that are for good for you and your life path. You cannot know exactly how you will feel in advance, so it is hard to prepare for it. They say, a transit never comes unless you are ready for it. So in September, you will be ready

Moon conjunct Saturn
Situations that require you to keep a cool head will work out well under this transit. You are not easily swept away by your feelings now, enabling you to effectively tend to business. Authority figures or people who are older than you could figure prominently now. A heightened awareness of your responsibilities, or taking on new responsibilities, characterizes this influence. It's easier for you to buckle down and work, organize, and plan. What you output now will benefit you down the road, as it's likely to be solid and realistic. This is a good time to make plans and lists. Some of us feel lonely or unsupported under the influence of this transit. Others welcome the feeling of self-reliance that comes now. A domestic problem or a burden might drop into your lap now, but you are likely to handle it well.
And Saturn transiting your 9th house.
This period in our lives is generally dedicated to self-improvement. We are developing our ideals and our commitments as transiting Saturn makes its way through our ninth house. Ideals and spiritual goals that we may have taken for granted or worked with for many years suddenly seem superficial or not particularly useful to us. If we have been studying, we must watch for a period of questioning exactly what we are working towards. Does this line of study match our true selves? Some of us begin new studies as we unconsciously prepare ourselves for Saturn's next house transit. But most of us come face to face with our self-defeating attitudes during this period of time. The ninth house is a fire house, and it has much to do with our outlook, our sense of adventure, and our confidence. It also is associated with our faith, hope, and vision. Although its attachment to such things as higher learning and travel might mean that a Saturn transit to this house will affect these things, but for most of us, it is more about taking a closer look at, and re-assessing, our attitude and confidence. At the beginning of the transit, we may feel a little somber. The blind faith or optimism that may have carried us to date comes up for inspection. Are our belief systems sound? What do we stand for? What kind of future are we working towards, and why? The spirit that drives us and motivates us to move out and beyond the everyday grind comes up for inspection. By the end of the transit, we will have re-worked our spirit, and come face to face with what it is that offers us hope and optimism as well as that which fuels our drive. The initial entrance of Saturn into our ninth house may cause us to question ourselves, but by the end of the transit, if we work hard at self-improvement, we will have replaced our old spirit with a re-generated one. We will be one step closer to knowing where we are headed, and we will have re-built faith in ourselves. A shaky feeling that causes us to sputter and avoid risks will be replaced with a more mature attitude towards adventure and facing the unknown. We let go of self-defeating attitudes that have been holding us back, we recognize exactly where we have been overdoing our expectations, and we find new ways to nurture faith, hope, and vision.
All the best
