Marian, take what your feeling as a sign. It may be to early to start dating casually. I know its hard and you have needs you want met but really there are ways to take care of them yourself....
You are accomplishing many things now.. and thats a good thing. Take baby steps and when your ready you wont have the rollercoaster ride going on in your stomach and it will feel right.
Hugs,
Jewel
