I possibly am being unreasonable but need to hear what others think before I ruminate much more.
I'm going through a hard time at present. Someone close to me is likely dying and I have PTSD about something that happened a few months ago. It's unusual for me to have these sorts of problems (I've been very lucky up until now) and my MH is all over the show.
My best friend and I have been through a lot together, but tbh it's been me to support her more than the other way around largely (I think). Including a period two years ago when she was depressed and went through a stage of getting drunk and quite mean to me, so I stopped drinking with her. She's still not in the best space now, but has been excellent to me recently, an amazing friend really. I've come to rely on her support quite a lot, although we still do take time to talk about her stuff too.
Last weekend we went out and both got drunk for the first time in a long time, which is unusual for me and was a mistake. I'm not a big drinker anymore, but she is and I got swept up in things. While drunk I was all over the place and said some mean things to her. I said I feel like she used me sometimes, and I brought up the horrid things she'd said two years ago. We had a fight and it was terrible.
I was sorry right away. I sent apology messages from the cab home, and the next day wrote her a long email saying sorry and how much I appreciated her. Then the day after I messaged again asking if she was OK. I also said to her that I'd learned my lesson and I've decided not to drink anymore while my MH is poor.
She replied that she didn't want to see me anymore and could I please not message anymore.
I am devastated. I feel like I'm losing a loved one to cancer at present, but have lost my best friend too. I feel like I'm also losing myself, because I never used to act this way. I feel like I've done all I can to make it right but don't know what else I can do apart from let her be.
But - I also feel let down by her. I thought she'd accept my apology. I've accepted plenty from her in the past. She knows what I'm going through too, and knows how badly I'd take this.
AIBU to feel let down, as well as devastated?
