Well you did not give me your time or place of birth, but with what I can read of your chart, it's no wonder this is a challenge for you. You have a T-Square with the Moon, Jupiter and Neptune. The addiction issue is clear from Jupiter Square Neptune. You feel everything "big". It can be difficult for you to discipline yourself, and find an outlet for your talents, because emotionally you are swinging from one extreme to the other. Top it off with your sensitivity and the slightest thing seems to tip the pendulum from one extreme to the other.
I can relate, I have been through a lot of what you have. There is hope. I learned that I had a choice what energies I permit in my space. I have learned where the boundaries need to be for my emotional health. It was a simple matter to decide to do this - I just needed to learn how to do it.
I found some of the answers I was seeking though The QuinnTessential Experience (TQE), an experiential personal growth class. If you can't afford to go to the classes, I recommend a book written by James Roswell ("Ross") Quinn, one of their facilitators, called "Controlling Others for Love and Profit" ("If you believe that, then you better wake up. Controlling others is not the solution - It is the problem."). Don't be thrown off by the title
Other ways I balance things out? I meditate every day, both morning and evening. I use the concepts in Ross's Centering CD. I journal about my experiences, I keep track of my emotions and what triggers them. I set my personal boundaries, and stick to them. I suspect that you feel an awful lot of responsibility for others, and this is the reason you feel so exhausted all the time. I don't take responsibility for other people's happiness anymore. I still want to help others, but the funny thing is, when I am able to release my attachment to the outcome, not only am I more effective, I am a lot happier.
