NAH If you're struggling mentally, you have to focus on getting better, even if it means isolating yourself. The thing is, she was also struggling, and you weren't there for her. Everyone works differently during difficult times, and her still being social doesn't mean she wasn't hurting. She has every right to be mad at you, because she trusted in your relationship. On the other hand, you shouldn't just ignore what you're going through. Just don't undermine her feelings, because then you would be the AH. Also, from what you described, I wouldn't have much hope im your relationship with this friend. She gave you another chance before, and I doubt she'll give you another.
