I’ve lost 5 friends and I’m spiraling

In the past 4 months I’ve lost 5 friends. In October I had 3 best friends (one for 4 and a half years, one for 13 years, and one for 2 years). I decided to stop being friends with the 2 year friend because she would be passive aggressive and mean to me, but when we were talking and trying to work through it, I felt like she wasn’t putting in a lot of effort to repair things bc she would take over a week to respond sometimes. My best friend of 13 years cheated on her partner with someone I was seeing and then after some conversations I realized the person I had been seeing had been lying to me about their intentions with our relationship and I felt taken advantage of. My best friend and them got officially into a relationship and I told my best friend how hurt I am about everything and we haven’t talked in almost a month. I thought she would try harder to try to work through it. Two friends I wasn’t super close to but had been friends with for one or two years just stopped texting me and slow faded out of my life And then I made a mistake that hurt my best friend of over 4 years and she hasn’t talked to me for over 3 months. She said she’s going to reach out soon and she wants to talk about things, but I feel like there’s a pattern of people not caring about me very much and not prioritizing me, even when I thought we had a really strong and close friendship I’m having a really hard time not spiraling into fears of there being something wrong with me or that I’m going to keep getting rejected and be alone forever and I want to reach out to all of them and beg them all to be my friend again. I want to ask for reassurance but I know I’m not supposed to. Maybe if anyone has any similar stories that they could share to relate or could just say something kind or supportive that would be great. Thank you
