Everything I do seems to be complete useless, stupid and just agonizingly boring. I usually really like my work. Learning Programming languages, solving Problems, and enjoying the small rush when something finally works like you intended. But now? Everything sucks. I know that it's just a down-phase, but this does not help me at all. And I fucking hate myself so much that I can't just be like "Yeah it's a bad day, but I still manage to get my shit done." Why can't I be "normal"?
If you knew someone else was having the same experience as you, would you feel hate for them when they're not able to get their shit done? If the answer is no then maybe knowing that can help relieve some of the self hate you're feeling over your circumstances.
I suspect you may even feel inclined to provide empathy and support for the person having the same experiences as you. If that's true, then you know people having your experience deserve empathy and support. You're one of the people having those experiences so you're deserving of the same as others!
