How to heal when you don't know what has to be "healed"?

I am 17 rn, and I know I have anxious attachment. It's so bad at times, my face heatens up so bad, my heart beat becomes irregular and I js wan to fucking stop all of it.

I want to be in relationship without carrying all this emotional baggage bullshit. And Ive gone through a few articles which, to conclude, has the same crap "label your emotions" um yeah ok? I feel anxious. "Take therapy" I know I js don't have the money. "Tru to heal from your past wounds" but wtf are these wounds?? I don't remember shit, except a few shots here and there ofc.
