Who called from 7403882377

I don't know who this is but they know about my personal life and are tellin me to kill my self

First off don't listen to them. They're not important. You, on the other hand, ARE IMPORTANT!   Remember that always.
Secondly, for text messages: forwarding any text message spam you get to the short code  “7726,” which spells “spam” on most phones, to alert your network operator to the abuse. ATT won't accept 7726 But they will accept BLOCK and return a message that the web site is blocked. forward the texts to 7726 or BLOCK, depending on your phone carrier.

Hang in there! It will work out.

Thanks-did not see that one. That's a fair question/we'll most likely never know. I'll borrow your link.
