How do you help to tell someone how to help themselves out when they need help?

I've been really demoralised lately.
i blame no one but myself.
I was told that i'm horrible.
i really do think i am.
I've just been to blinded by what i do best to have been able to open up & see anything that ive done wrong.
I've hurt the people around me.
I've also disappointed the people who meant the most to me.
I miss the person i was, it must be so pointless for anyone right now to talk to me.
I am hopeless.
I need abit of time to regain my strength.
I've lost it.
Ive been hurt, pretty badly & usually, it would be someone's fault.
" who hurt you? tell me, i'll kill them "
I'm so used to listening to that only to come to this day & tell you that i did this to myself.
I dont deserve anything great at all.
& my morale is just..
i think im shattered, i tear everytime i think about it.
I cant help it, im lost.
