How to deal with my life...

I really dont know how to deal with my life anymore...it's been so screwed up n i've been soo unhappy but i dont even know how to change that...=(=(=( I just feel like i face everything by myself with nothing but tears and fake smiles every day...everything just suckssss......!!!!!!!!
Is my life meant to be like this or is it that im too useless till i dont even know how to make things and my life better?? Am i useless to other people too??? I dont know what others think bout me...I mind how people look at me...i cant change that...
I dont know..........I guess i need my life to change...but how...? Nobody can help me but myself...Im really really tired of this.........................................i have no strength to carry on my life already............
