first relationship breakup

This is my first ever relationship and my first everything. After 6 months we broke up due to the fact that he couldn't handle a relationship while depressed and will not seek professional help to get better. 
I feel like everything is my fault and I am the worst person ever. I don't know how to feel or what to do I'm so overwhelmed. He broke up with me 3 days ago and it was on my bed and he had to say it THREE TIMES for me to finally get it.
He stayed with me and hugged me and wiped away my tears but I doubt that it helped and I'm hurting so bad.
I just found out that my friend gave him advice to break things off if he felt he needed to the day before he broke up with me and finding that out just hurts me more. 
I don't know what to do because all the advixe everyone is giving me is full of cliche statements and breakup stereotypes that I feel like don't apply to me.
