I don't know you personally, but please do not end your life. Even as a stranger online it does get better, whatever you're going through there is always a way out and there is always something better waiting for you.
Coming from someone who has attempted before & is currently on a pretty good path of getting better, I've been in an extremely dark mindset multiple times before and I'm doing much better. I'm more happier than I've ever been & I firmly believe the same can happen for you too, even if you don't think you can make it.
Improving is not a linear path, there are always very low moments in your life & other times that feel amazing. Low moments can last for awhile, however it will get better. I promise. 
Please take care of yourself.
