What to do - Best Man/woman/person

Hi all,


So it's maybe not the strangest situation ever but my OH and I decided to finally get married next year and I am really struggling with the idea of who to ask to be my best (wo)man so figured I'd ask for advice.So for me the struggle is committing to someone to ask because - I'm the kind of person that gets super anxious about making plans so naturally drift out of friendship groups.- I also moved 3 hours away from my longer term friends 10 years ago and not once have they visited us so I feel like they would maybe not wanna.- it feel guilty putting that task on someone who doesn't see me as a best friend anymore
Also family is kinda out of the question in my own head for the same reason as point 2 above.
Has anyone been in a similar situation? Because it's causing me strangely more stress than it probably should.
