I consider myself practically a dropout since I was put on academic probation and on the brink of getting suspension from the college--but I never gave them that chance. I quit!

Well, I was just like you, I graduated at 17 and started college, community college(because that's the way to go! ^.-)--and did horribly. I had no direction in life, and games took up most of my time; it felt terrible. I've tried uninstalling games, cutting down game time, thinking positively and just trying to enjoy going to school. It wasn't working. Then I realized what the problem was--I was taking GE courses. The same boring highschool classes ALL OVER AGAIN! Plus the fact that I had no clue what I wanted to do which definately did not help to motivate me. When asked what I was majoring in, I really wouldn't have an answer, and it embarassed me. I felt like I had disappointed my parents tremendously. I was told by many that 'it will come to you'--well let me tell you, after 3 years of heading towards no direction in particular and failing the GE courses not because I didn't understand the material--I understood it perfectly, but because I couldn't handle sitting in a classroom learning the same boring things over again, it really did come to me.
One, of the many customers who have spoken to me about not having a major or direction in life said to me, "Don't worry about it, once you find what you want to do, it will all fall into place. " Sure, at first I thought, yeah well, he hasn't seen my grades yet and how I had pretty much ruined my transcript, he wouldn't be saying that if he did. And then one day--I was having another one of the same conversations I have had with my boyfriend many times over about: feeling like a loser, having no direction in life, disappointing my parents, and feeling...trapped/stuck in life. He asked me why not pick up Interior Design; the question left me perplexed. Why not? The thought had not even come to my mind that I would want to major in anything that was remotely related to interior design, and yet, then and there, I realized that interior design was something I've had a passion for since a child until this very day. Something that I loved so deeply, yet had absolutely no knowledge that such a strong passion for this particular field existed in me.
Let me tell you--everything
did fall into place. The feeling was phenomenal. I found a school that offered a bachelors degree in interior design, applied to the school right away and got accepted. I had never felt such excitement and eagerness to start school before. The best part? I didn't have to take enormous amounts of GE courses. Sure I still have to take some; but I actually get to take courses related to my field of study now instead of being bombarded with pure GE courses the first 2 years! All of a sudden, I knew what I had to do and I knew exactly how to do it.
So
really--it will come to you, and when it does, everything will fall into place.
College isn't for everyone, I definately agree. But you know what? It doesn't hurt to find out. I suggest you stay in college for a bit and think of it not as a means to an end, but as a learning experience to expose you to what your passion may be. Sure, take random courses that you've never thought of but think you can bear for a semester or so, maybe one of the most profound, preposterous professions will work for you, and you will be astounded.
Do not count your time. I don't mean completely lose track of time--just don't think of college now as a waste of time, but a learning experience.
That's really about all I can say--feel free to PM me with any questions!
