"Hi, I know I breached your boundary before and I'm doing it again and I'm sorry. This is the last thing I want to do to you again I completely understand if you're unable or unwilling to help, and I respect your decision either way. I'm willing to change and comply to your old and new (if any) boundaries you set and from your perspective you must be deeply hurt so much to do something against your will out of necessity when I started hurting both of us. It's on me and I'm responsible for starting therapy too late after our relationship already shattered.
I'm in a very serious situation now and I don't have much time left due to a mental crisis that only exacerbates when I talk to any other person. You're the only person I feel safe with, and I really need your support right now, I love you. Can we please talk?"
Today I wrote this to a friend who blocked me 8 months ago (which feels more like 80 years of infinite pain) because I mistakenly breached his boundary after he muted me out of nowhere saying that he need a break and don't know if he will ever come back and guess what he blocked my alternate account too without even replying
