A little background:
I used to be pretty good friends with a family member, and we rented a house together along with some other family members. I got my first job and things seemed okay until my mental health took quite a turn for the worst. It would be bad enough that after work I couldn't bring myself to go home or want to talk to anyone and couldn't keep my promises to hang out with them. I felt like a total mess 24/7.
My family member became upset and we basically stopped talking. Some of my other family members tried to get answers out of me but that didn’t really help. I decided to send my family member a letter saying I wanted to try and explain myself and we began to exchange emails. I’m not sure if it was that I didn’t explain things very well or something, but they didn’t understand, and I decided to break it off. It felt like I was only hurting them.
I moved out and sought help and am doing much better now. I keep finding myself thinking about them and wanting to try to make up with them, but it's been 2 year.
How do I tell them I'm sorry and want to try again for the second time after so long?
