Don't let anyone including your mom have that much of an impact on your emotions. I used to do the same thing but as you get older you will meet people who value your friendship. Thanks for coming to this site and you will find a lot of support here, if nowhere else.
Please ask for help. there is help for all of us struggling. Please don't carry this all alone its too much for you to handle.
Good luck and God bless.
ok focus whats your favorite thing focus on that
now got to a low light room listen to calm not depressing or rock music
just drift away all you see is that thing
now day to day just relax dont listen in your head focus and picture that thing
feel her voice or whatever troubles bounce off you
go for a walk
good luck and hey life and you always matter
I forgot to add something sorry,
*I have constant suicidal thoughts pretty much constantly...
