Maybe you are upset about something? Air it out...
Nothing wrong with you, just try to stay happy the whole day and night!
clinical depression or bipolar. You might wanna see a professional.
That sounds like me. Did you go through a break up? Or something has happen in your life? I broke up w someone and night time is the hardest. That is when I am the lonely. :( hope things get better for you.
*cough* bipolar *cough*
There's something that's bothering you but you're not willing to deal with it. That's one possibility. Another is that you have clinical depression.
