you can start by recognizing the things that you are able to do on your own, look at your strenghts, see where you are independent. praise yourself for those things. then begin to make small decisions on your own. if you think of something that you want to email, call T about, say to yourself, "wait a minute, can I make this decision on my own?" and if it is something simple, make a decision and enjoy the positive outcome knowing you did that all on your own. the more positive outcomes the bigger decisions you will be able to make on your own. soon you will be much more independent.
