I think you should look at your MN name... Hadenough, right? But you're not the first person to choose that nickname... there's (at least) another four people here who feel or felt like you do, right now... (unless they're all you, and you just keep name changing!).
You sound depressed. There's no shame in that. The pandemic shizzle is making people who already feel low feel even worse. Sounds like you need to take steps to sort yourself out, and I appreciate that's hard to do when most of the things we'd do to make ourselves feel better aren't available right now, but...
...there is still stuff you can do to feel more chipper. Sleeping properly, looking after your diet, exercising, going for walks, signing up for groups online, doing yoga, going to see your GP and getting some pills to tide you over, making plans for the future when all this covid shit is over. You can top yourself, sure, but... I'm guessing you don't really want to die: you want things to change, and only you can make those changes.
What would your 'perfect' happy life look like? What is it that you want that you don't have? Once you've worked out what it is you really want, work out how to get it. What steps do you need to take to get you closer to getting what you want? Write it down. Make a moodboard, cut pictures out of magazines, get the coloured pens out. Get some inspiration. Then, figure out a way to turn your dreams into realities.
