I'm depressed and not immediately telling my now ex-friends
Why not now? Why have you not told them how you are feeling?
I remember all those shit we went through and I'm tired of it all.
You will be ready to open up to them about it eventually. It is okay if you are not ready to talk about it yet.
Nah, I'm going to wait for them to ask me... I'm still not ready to talk about it.
That's perfectly okay to feel this way and do things on your own time. You might not be ready for what they could say, so how about trying to work on yourself first and get into a better headspace?
