I think I have abused dog syndrome

For those who do not know what it means:

I do not know how to overcome this, I do not want to seek out the positive reinforcement because I do not want to be hurt in the process, and I also feel like an attention craving whore

What do I do, and do not make some gay response saying 'just put yourself out there' what is something that I can do alone
Same, idk what to do either
