I know exactly how you feel. I have water as a dominant element too. I did a merqury square that helped a lot. Beside this I had to program my mind by acknowledging my emotions and my reactions to certain situations or behaviour from people as it really took a toll on me from day to day basis for certain periods (astrologically).
Hang in there, you are not alone, and you know what? You'll be fine. You have Satan and the Gods, you have us.
Whenever an emotion pops up in the head or just starting to swallow you. Ask yourself questions: why do I feel this emotion? What can I do to control this emotion and thought? Analyze it, focus on your reaction to it. Your body movements and fysiology.
Then, find yourself a safe time. A safe haven in your everyday where you deal with certain psyches. This can last 30 mins or an hour! Whatever suits you. Try to tell your mind you will deal with this emotion or issue later when you have the time and can think properly. Ask Satan and the Gods for guidance in how to mature and grow emotionally and to stay in control. Where you are able to heal and deal with your emotions in a constructive and healthy way. This help is gonna be quite subtle, so be sure to listen! Or just feel, in your case. You have immense power, we all do.
I know the hurt, the sorrow, the pain, the grief, the agony...these dreadfully destructive consuming feelings/emotions that this world put on our pure and sensitive souls. It leaves scars. But, the world isn't just grim. It is wonderful as well! I acknowledge the horror, yes. But I choose the good and brilliance this world may present to me, and under Satans guidance... Life is golden! I am really in a happy state, I am fulfilled, and I finally know exactly who I am. Which paths I were meant to take. This comes in time so have patience! My point is, this is a learning phase for you, and you will conquer, that is all!
Stay strong comrade!
