A couple of suggestions:
1. See if the college or university you've selected will allow you to defer your admission for a year or two. I think it's a free option, and if you figure out you want to go on after a year or two, then you don't have to reapply or anything.
2. You're totally in the same situation I was and my oldest son was when we finished high school. I ended up going to college for 2 1/2 years, then stopping out and working for 1 1/2 years, then finishing my undergrad. My son went for 1 1/2 years, has stopped out and worked for about 3 years, and is just thinking about going back part time now. I think if you went now, you wouldn't be happy and probably would struggle with success even if you've had success in high school, because college requires you to go for you, not for your parents or friends or what society expects.
3. Based on #2, you have the relationship aspect with your parents (or whomever in your family is pressuring you to go). You need to talk to them with as much respect and maturity you can muster and explain that you need to find your own way in life and that you think you want to go a different direction and could they support you in that - emotionally mostly, and financially if they are able and willing. Almost all parents who want their kids to go on to university generally want their kids to be happy and successful - some will consider supporting a trade school or apprenticeship, more probably won't.
4. Talk to your high school guidance counselor - if they're any good, they can talk with you about non-college alternatives and how to connect with the people you need to, find the jobs you're interested in. You can also just be a bit unusual and just walk into an auto shop and say, "Hey, I want to learn this stuff and will work here for free if you'll just teach me." You might be surprised at the positive response you'll get. Hint: you may need to try 10 or 20 shops before one says yes.
5. Overall, I just want my kids to be happy, healthy, safe, and self-sufficient. Being self-sufficient without a college degree is certainly possible. Depending on the path you choose, you should know that statistically people with degrees (a) make more money over their lifetimes, and (b) have lower (i.e. better) unemployment statistics. As an adult you get to make your own tradeoffs and decisions about this stuff, but you'll get more respect in that conversation in #3 above if you acknowledge that you're making this decision after having considered both of those statistics. If you say that you're the exception to the rule (and you may be) and you'll make $1M doing high school play set artwork, then your audience may be less receptive to your message and request.
6. Some colleges and universities are more focused on hands-on vocational training and it still leads to a degree. Look at Idaho State University as an example. It may be a compromise situation where you and your family are happy.
7. As a general strategy, you might consider moving more than a day's drive away from home. I'd suggest a city in another region where you might have an aunt or uncle nearby. That way you still have family who might support you (like on holidays) but you can be out from under your family's control. If you can manage to be successful for a year or two going your own way and out of their control, they might come around and say, "OK, we didn't think it was a good idea at first, but you're being successful in your own way and you're happy, so now we'll get behind you."
Good luck!
