You're scared because you want to live and don't want to make another attempt. I'm sorry your frightened. It's hard. For me, sometimes I am anxious/depressed one night then when the next night comes, it's a lot better. You may have a good night ahead. Please tell your family if your feelings don't subside. Your fear is telling you to reach out for help. Don't be afraid to ask for help.
Sincerely, Myst
