I understand too OP and sorry you are experiencing this.
I have had times when I wished so hard for something to end me so people wouldn't have to deal with it being a suicide. I got breast cancer two years ago and I was kind of relieved - it wasn't a straightforward decision to have treatment but I got swept along with it and I'm still not sure it was the right decision. I do feel terrible saying that when people have illnesses that aren't treatable.
There was some relief in being ill anyway as I felt I could step out of normal life for a while as I had reached a point where I couldn't function anymore (although some people were still quite brutal, judging me for not being productive while too weak to sit up from chemo - that's another story). Maybe the cancer had also been adding to that exhausted feeling for a while before I realised I had it but it is also a life long problem that depletes me more and more.
In a way it was a simple decision to have treatment as I have two cats who I don't want to leave on their own. Maybe the fact that I took in cats in the first place shows there is part of me that wants to keep going. But dealing with life feels too much sometimes.
Nature has always been my main solace but it's being destroyed rapidly around me and has become another source of anxiety.
I never really get those who are cheered up by us not being bombed or starving etc, I am incredibly grateful for those things but the fact that other people in the world are going through that makes me feel worse not better - makes me more sick of the world in general.
I feel less alone and less like a weirdo having read all these posts although I'm also sorry you are all feeling like this.
I don't know what to say @Dontknowwhattodo223 . It feels trite to say I hope you feel better at some point but I do hope that you do. Anyway - solidarity.
