For context, I used to feel really bad especially on evenings for about 7 years now. The last 2 years I feel like it got better and happened less often.
I also used to cut myself, which noch I haven't done in half a year and less often in the kast 2 years as well.

However for the last week I'm just feeling empty. Nothing seems to excite me or bring even a bit of joy. I'm just feeling sad for a week now without a real reason why.

Never had this before. What's happening?
