friend rant cause im mad

I literally don't know WHAT I did to an old friend that I didn't already apologize for to make her act this way towards me. 

So I went a little crazy as I tend to do in summer when school isn't in session, and unfollowed a friend who hadn't been in contact with me for awhile. Which isn't  good way of coping btw it just made me feel worse, and I tried to reach out and explain and apologize and say how I missed her and felt awful. 

She basically didnt give a fuck about that said it was "okay" but clearly was pissed about something. I said sorry again and that I understood why she distanced herself from our old friends (but she also distanced herself from me) and I said it hurt when she wasn't talking to me and I didn't know why. I said I would be there for her if she ever needed anything and all she said was 

"Thanks." 

oh it made me so pissed off... I tried refollowing her and she straight up declined my fucking follow request. I haven't tried refollowing her again yet but I might. I know I should probably move on but I feel like what I did didn't warrant this kind of response. She has had friends with mental health issues she has them herself, she has had friends who unfollow people and would say "oh thats something they do" but go forbid I do it now all of a sudden I'm trash and a horrible person? 

This has bugged me for the past month and no matter what it still makes me mad and sad. We would've known each other 15 years this year. I was always there for her I always stood up for her and this is how I'm treated for fucking up once. 

Anyways rant over, I'm going to the fair tomorrow with friends I haven't seen in awhile and I'm so excited :) so at least thats something good!
