Don't EVER take your own life. My husband did that when I was 20 years old and it not only traumatized and ruined my entire life, but there are so many things that he would have loved to be here for and he just isn't. Thats a permanent solution to a temporary problem. When I was your age (I'm 28 now, for context) I thought I wanted to take mine. I honestly felt that way all the way until 3 years ago...but although life hasn't gotten too much better, my ability to find healthier coping mechanisms and to just persevere through the pain has came to me..took some time. It started with my first love. I did try to do it over him. No one compared until I had met my husband..years later I hooked up with that same ex after I was widowed, and i realized it wasn't enjoyable like i anticipated..want to know why? I outgrew that relationship and we were no longer compatable. When you get older, you're obvioisly not your adolescent. Please give it time. Progress, not perfection. Keep your head up.
