I know what it's like to feel that low I'm sorry to hear you're feeling this way *hugs* . This site is great, so if you want to talk or vent, feel free to! I hope you do.
Do you know why you're sad? Why you hate yourself? Did something trigger it or is it just so dark you can't really explain it? I know it feels like the end but you will be ok and it does get better. Keep talking
