Is it normal that i feel so sad and lonely all the time

No you have depression. My mom had that and you need to go seek help before you end up killing yourself.

Hear that lonesome whippoorwill
He sounds too blue to fly
The midnight train is whining low
I'm so lonesome I could cry

ya its normal.

Actually let me tell you something, I know a thing or two about being lonely. In fact be glad you are lonely then having some fake ass friends who talk shit about you, won't stick up for you, and copy you to take their grade from you. If anything being alone is a lot more healthy than not being alone. I actually been through soooooo much shit, yet i'm alone all the time. People may shit talk about you all they want cause your alone but let me tell you .. It's better than having drama in your life, it's better than having shitty ass friends and stress. But at the same time.. I know what your going through. Your alone, you want someone to talk to you, maybe you want some attention, you probably want something more? Don't forget , if you're still in school or something you have teachers to communicate to. Are you involved in music or something? Art?? If not try something like that. Or if you really don't, try to at least make friends. I know it's cliche to say but that's the only reason why your "alone" right? Just smile when you make eye contact with someone. Just talk around, say hello to a classmate daily, be kind. It's perfectly normal and totally okay to be sad and alone but not too much. So at least try something . I believe you can do it. There is always hope so don't give up. Best of fortune!!

dont you have friends or family you can talk to and do stuff with?

is it because your feeling anti-social?

do you feel sexual alot?

sometimes being HIGHLY sexual can make people feel anti-social

if thats the case, id say quit the porn for a while

or cut down HEAVILY on it

Loneliness is a self-inflicted disease. The only cure is to force yourself to go out and socialize.
