First many hugs.

IMO I think we heal in stages. While you have gone through allot and sound better in many ways the fact that you feel unsettled inside and want to go to therapy means you are looking for the next chapter of self work (IMO). I have gone through this after taking a break from therapy before etc.....

I have a friend who to is a single mom and has nothing extra to pay for therapy (she was in therapy before). She did find a therapist that would take her on probono so perhaps if the local mental health clinic doesn't work out perhaps you could find a therapist that would take you as a probono ?

Keep us posted .
