I have a terrible memory so I can't remember at what point this happened, I think it was a year or two ago maybe but this person is back in my life now and I think wants to be friends again and also I know for a fact was she was very confused as to why I cut her off.

Basically what happened was during psychosis at that time I became extremely paranoid, and I was convinced that all of my friends were plotting against me behind my back and that they were constantly talking bad about me and laughing at me and thinking of ways to betray me.

This led to me cutting off random people (Some were justified tbh lol) but it included her because I thought they were evil and planning on hurting me and I gave absolutely no explanation. How do I better this situation and make amends because I know she still wants to be friends.
