Finding direction?

I'm 19, today all I've been thinking about is what I've been doing the past couple years. I haven't figure out what I want to do, work at a shitty job, can't get enjoyment out of the things I do(school, bjj, life in general). I just feel consumed because I've been so aimless, it hangs over me wherever I go. I can occasionally stop thinking about this until the thought starts creeping back in my head. I feel as if I need to truly struggle to figure this out, as if I need to start my life from scratch and build my way up. Some things I'm grateful for are my family, even though I had a rough childhood they provided everything for me, but I feel like they can't give me anything else and I need to figure it out on my own. I've saved a large sum of money from working my ass of at a shitty waiter job that I've grown to hate, I plan on quitting soon. I'm currently in CC, my plan was to finish an AS in networking, get a shitty computer job that pays well, then have money to do whatever I want. The thing is I don't know what that is and it's been bothering me and interefering with everything else since I started thinking about the future. I feel as if it's the universe telling me I'm going the wrong way or something. Anyways I just wanted to get my thoughts down.
