Some of my friendships ended recently and I just feel like complete shit

I have been going through some stuff and I ended up hurting people close to me, at the same time I feel like we weren't really compatible in the first place and they had their own shit going on, but we did have fun till it all came crashing down- largely due to me.

I've already said everything I could to them, yet I feel 'defeated' bc I couldn't end it on my terms, I feel completely dejected and don't know what to do.
