Please help... sad alot...?

honey, you need some serious help. PLEASE talk to your dad immediately. Believe me, so many people go through depression and try to handle it on their own. Dont' follow in their footsteps. Talking to someone and getting professional help is the only way. Until you can get help, I suggest you try praying. Ask God to take these horrible thoughts from your mind. Just keep repeating it to Him and believe me it;ll work.
