I totally get it. Honestly, I've found just being by myself and taking a "break" away from people and whatever is making you stressed or depressed can be helpful if you have the means to. Even just decompressing for an extra hour in bed or in the bath can help you process things better. I found it super useful after I attempted suicide years ago---being meaningful (i.e. doing it deliberately) with our alone time (vs. being lonely or feeling inadequate) is way more valuable than people give it credit for.
Nonetheless, I hope you work out whatever is happening. Life is difficult, but it doesn't mean there aren't good days to look forward to. I believe in you! :)
