Is it normal to feel this miserable?

[?]

I'm 15 and having family issues. I feel alone even though I have friends. I hate being around people but I'm sad alone too and I always fake a smile. However, whenever I read my twitter and facebook feeds a lot of people say things like "no one knows what I'm going through" or "I fake a smile through life" and it makes me feel like my problems and feelings are normal and common. Should I get help or just try to get over it?
Thanks!

If you feel like something is wrong, you should definitely ask for help/advice from a trusted family member, or someone that you could just talk to (for example, a school counselor or parent). Holding in feelings like this for a long time will only make things worse.
