My friend is in a deep hole and I don't know what to do.

Stay with that friend for as long as you can, so long as you don't let their problems render you useless to them and yourself
Thank you, but sometimes she's always having a hard time. And whenever I try to help, I feel like it ends badly.
I can understanding, especially bc right now, I'm like you're friend. Remember? You can't help anyone without helping yourself first
