Hey, I want you to know that I get you're going through a lot, but you should keep going. I know how it is to feel like at an all time low, to feel like you don't want to be in this world. To feel like you want to leave and never come back.
But there are still so many great possibilities in your life you'd be throwing away, even if it doesn't look like it. You know things will change eventually, you know you will get out of your situation. While you're waiting anxiously for the future to come, try to stick it out and make the best of now, I don't want you to spend your life now being miserable. Even if it is hard to stop being sad, just treat yourself once in a while and do activities that cheer you up.
I can't help at all with your situation obviously, but if you need a distraction from your everyday life, I'll try to help out and keep you entertained.
