What must i do? Help?

My reality is out of sync, with the one that is actually going on. In my mind i expect things to be more intense, chaotic, lively, exciting, dramatic, and i try to do things and carry myself in that way. But real life is too slow and lacks the excitement. I cant live like this anymore. Ive always had strong strong cravings for adventure and wild experiences. Thats why i dont participate in my own life. I lived as a hermit during my teenage high school years. My reality was always warped against everybody elses. Im 19 now. But even now i feel kinda old, like 50-60. Cause ive thought about so much things. Just overworked my brain. And imagined things in my head before they took place. I dont enjoy spending time around people anymore, i dont think i can gain anything. I dont have a girlfriend, but i know i wont be that excited. Ive exhausted all my mental boundaries, and i havent let things happen spontaneously. I just cant. I try to plan to much thing in my life. I just cant chill. Ive thought about how id like to live my life and what id like to do. But now im bored. Nothing surprises me anymore. Ive been through alot of things. And now i feel like i know alot. I want things to be like in television, music, etc. I just need to have that fantasy. I think id enjoy being stranded on a deserted island, and explore and live like that, in the tv series Lost. I cant go on anymore
