Can you relate or recommend help for fear of attachement/affection (selfhelp books/ online therapy) ?

I have a serious fear of attachement bc i get attached easily an the get hurt, it happened to me a lot.. whenever someone approaches me or shows they are interested i freak out, and my anxiety gets the best of me

I neglected this until the day it happened with someone I really liked, and it hurt the most bc they got they misunderstood my anxiety/reluctance for disinterest... that just simply killed me...

So i decided i have to do something about it. I can't afford therapy so if you know any online service for free ( not sure there is, though) or selfhelp books plese tell me
