Dear (Names)
I'm very sorry for how I treated you.
I'm trying my hardest to be a good friend but sometimes it just doesn't work out as I planned.
I've been struggling with this whole pandemic, and I just can't deal with my head anymore.
I really love you guys as my friends and I want it to be a happy friendship again!
I am so sorry about treating you guys badly.
I hope you can forgive me.
Sincerely (Your name)
