I'm a little messed up?

Probably won't be very long, just flowing with a post...I'm happy and sad. But not in any particular pattern. Small things set me off sometimes and put me in the absolute worst place, or other times large devastating things will barely phase me. I have a decent life I suppose. Just got promoted at my job, have a nice new girlfriend (after I broke up with the old one whom I'm still in love with but that is a whole different story), have a few pretty good friends, and a loving (though small) family. I really don't have much to complain about and I really am happy a good portion of the time.

Anyway, I don't know where I'm going with this. :D I don't have many people to talk about this stuff anymore, so I felt really desperate to share...When I do get sad it can last a few hours or a few weeks. I can be a little sad, or I can sit there pondering why this world really needs me. I don't really openly share my sadness with people anymore, I used to be more open with it but I feel it scared some people and I don't really have that kind of open connection with anyone in my life now. Again, not sure where I'm going with this or what the point is..Sorry if its random or a run on or some other thing like that.
