anxious attachments in romantic relationships

hey chat guess whos back!! talkin abt anxious attachment today bc its been KILLING ME lately T-T so i see myself as a very loyal person, and im starting to think thats bc i fall so deeply so quickly. i attempt to slow things down in relationships, but its super difficult for me ... chat i am SO COOKED!!! ill spend like 13 hrs on call w some1 and then they wont text me back for 2 hours and ill tweak out ._. WHYYYYYYYYY its so unnessecary too bro ik they like me too i jst need constant reassurance !!! i try to self regulate but w my autism it makes attempting to self regulate my emotions even worse T_T and EVERYONE i talk to romantically is like "yeah i love it when ppl text me a bunch haha <3" AND THEN I DO and then they go "yoinks! big texter over here.. lil too much texting for me" (at least thats what i imagine they say to themselves) and then wont text me back, so i text them even more (bc i just LOVEEEE to dig a hole for myself) bc i feel abandoned, so that confirms their idea that i am very "needy" (which i prolly am) or im annoying (prolly am pt2) so they stop talking to me and i am heartbroken bc im sensitive </3 ITS ALWAYS A TALKING STAGE TOO x_x i keep trying to fix this but /gen my fear for abandonment controls every aspect of my life </3 if anyone has coping skills or ways to fix this lmk bc im constantly tweakin over ppl i barely know :p

P.S. I KNOW THIS IS UNHEALTHY!!! im trying to fix this bc i hate checking my phone every 2 secs to see if theyve texted me + shouldnt be manipulative <3
