I wish I knew exactly what to say. I've felt this way before many times. It's horrible. Please realize that you are worthwhile, you are precious. Only very sensitive ppl get very down like you are. I'm not religious but when I get that down I pray. I cry, I try and write out at least one positive thing about myself. I've attempted suicide 4 times. Not fun. Please remember feelings and moods pass and change. You are loved.
