I don't know what to do...?

is it normal to feel uneasy at your own home? I feel like I don't have peace, like if everyone and everything is making me want to cry but at the same time I have to hold it in and.. I don't know what to do.. I know I need help but I don't know who to talk to about it, I feel like no one in my house will understand and help me, I'm supposed to be better and be improving but I'm not and I don't know how to face this feelings anymore, I used to be so used to them, now everything is weird and confusing and frustrating and.. I hate this.. I fear I might try to end it all again but I have to push those thoughts away but it's hard and it's getting harder and harder and..

I need help
