Depersonalization?

Hey guys, I have a moderately bad problem here. Ok, so for the past few monts, I have been feeling very...off. I have had a problem where in some situation I get this really weird feeling, where I am kinda like dreaming. It has started to pick up in the past 3 months I think. It has gotten to the point where I have trouble doing a lot of things. I find it hard to leave my town, and even do many things in it. I feel like if I do anything other than longboard, go to work, or be in or around my house I get said feeling. It has crippled me socially. I Have left my town only a few times in the past few weeks or so. I dont go over my friends houses, stores, out to dinner, competition (longboarding), and many other things. When I try to do these, I feel very spacy. Its hard to describe, kinda like I am asleep and everything is a dream. I dont take note of what I am doing, and feel like I am skipping past seconds of my life when I dont pay close attention. I am a 15 year old guy and it really scares me when this happens. I do everything I can to prevent it, which results in a lack of being social. Im having a really hard time with it, and its on my mind a lot. Is it Depersonalization? It sound like it from the wiki article I read. I just need help and I would REALLY appreciate it if you guys could provide me with some. Ask any questions if you need to.
