Feeling kind of off....

So, I've been feeling kind of off lately. Actually, this is my blog, so I guess if I can't be honest here, then I can't be honest anywhere, right? I've been feeling off for a long time now. I have recently found out that being bi-polar runs in parts of my family....just sharing that information....I don't think I am bi-polar, LOL! But I wonder sometimes if I might suffer from depression. It's hard to know something like that, though....I mean, do I suffer from depression or am I just sad? Does everyone else feel the way I feel? Is this normal, or is something wrong with me? I don't know.
