Should I try to fix broken friendship again now?

I was in a severe depression and used my friend to help with that too much. I was also being a clingy friend. There were other things about mer that bothered her, but she never talked about them until she let everything oput all at once. I then spent the next 2-3 months apologising, but I did way too much and that made things worse up to the point of her threatening to get me in trouble (harrment) so I couldn't talk to her. I tried to fix things by ending every friendship I had (all of my friends were hers too) so she wouldn't have to worry abut me being wih her other friends. It's been three months since then. She's the best friend I've ever had and I'd really like to be friends again. Should I try now or wait longer?
