Agree with Sotto. Trust me I have struggled with the same thoughts. I was like I am ready to date, ready to see what is out there. But I am not... it is too soon. I had a bit of a panic attack a few months ago because I felt like I was getting old and really want a family. In the end though, everything will be OK... I know it! It'll come.
The gym helps me tremendously. Both confidence wise and socially. There is an interesting social dynamic that develops there between the regulars. Don't be scared of it! Hang in there
