emotionally unstable

now i have emotional problems..sometimes i crying, sometimes i laughing and sometimes i get angry with the things that i should not to. it's all happened at the same time. i feel like apart of me is dying. i don't want all this. it hurts me really bad. i want a life. a life that can make me smile again. a life that make me don't feel any pain. but i don't think i will get what i want if i'm staying like this. i'm not strong enough. i've been like this so many times and this is the worst times ever. whatever it is, i need to get up again for the last time (i hope so) and be strong to facing the challenges and unexpected life.
