It's a great start that your speaking out here atleast......
n it must be rough on u for sure...
Well on the bright side u ve git grandparents with u
I don't even know what to suggest u but the only thing I'm gonna tell u is..believe I youself.
Be happy thinking that ur loved ones are there somewhere happy n stay happy...
N belive your mom must be watching u from heaven n that she'll be sad if you are. .
I know how it feels to be lonely .Trust me, I really do..
But somehow try to push youself to do the things u love n don't leave yourself with any time to think or ponder on this sadness of yours...
And I don't talk Abt my problems either but u can try writing all your feelings in a diary Cuz they are best secret keepers n they listen silently....
I'm not sure I helped you but do try these...
And remember EVERYTHING WILL BE OKAY ........
