Hi there! I'm new here and am awaiting my results from my ADHD test. I do ALL the same things you listed your former friend does. I only realized this a few months ago when I was watching TikTok. A video was shown to me about some ADHD symptoms and it hit me that I did all the things. I'm 45 and my life FINALLY makes sense! Why I'm an underachiever, have low self-esteem, am overly sensitive with criticism and feedback, can't focus (or am hyper-focused, interrupt people, finish their sentences for them, why I have about 10 projects going at one time and never finish any of them. I think I learned from young age how to do what's expected at times but it takes A LOT of energy to do so.

If what happened with your friend can be salvaged, I'm sure she would appreciate you reaching out. Not that you have to be best friends or anything, but clearly you cared enough about your friendship to reach out here.

My experience is that I have a difficult time with relationships in general and therefore I don't have any close friends. I don't want to allow anyone to know the "real me" because I'm afraid they'll see all my flaws and reject me. So I guard my heart and don't let anyone in because the pain of rejection is far worse the the pain of loneliness.

Good luck to you!
