I think one of the most important and helpful things that you could do is not directly involved with seeking a relationship. This is tough, but VERY important. My brother had a lot of issues similar to what you are dealing with.
Add some structure to your life. So, you don't have a job that you have to go to at a certain time. Give yourself places to be at certain times throughout the day. Establish a typical day and (here's the hard part) stick to it. Post your schedule in a prominent location on a large dry erase calendar. Add any appointments or whatever to it and check it every day at the same time. In fact, schedule time to review your daily schedule. I know it sounds like a total pain, but it is a great tool to achieving your goals. Schedule everything from waking up, taking a shower, eating three good meals a day, taking a walk, whatever. As you meet your schedule each day, you will raise your self-esteem. You are meeting your goals (believe me, these are as valuable as many of my goals at work). Once you get into the routine, you will feel better, sleep better and have some fun doing things you enjoy on a regular basis (schedule them!).
Also, my wife's cousin made money by donating plasma. The catch is that your blood alcohol has to be below a certain level. If you exceed that level, they don't allow you to donate any more. Period. Give it a shot. You can make some money from it and help others.
There have been some great practical suggestions in this thread. Please give some of them a try.
