Having someone you can talk to about your feelings during the divorce process, may help with your level of emotional stress. I mean, someone other than family.
There are a lot of books written on the subjects you've described about yourself. I don't know about where you live, but some places offer community classes that teach how to meet new people and interact socially. There are tons of free information on Internet about building self-esteem, etc.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
