Hi. Please ensure you are safe as soon as possible. Please try and put whatever method you currently have in a place where you can't access it. I strongly recommend you call the emergency services or a suicide hotline.
There are tons of reasons to live. First of all, all of those who love you (your family, your friends) will miss you and be devastated by your loss, and probably traumatised by having to find your body. You can get better, and things can improve for you, even if it doesn't feel like it now.
Please keep yourself safe.
