I went to a community college and loved it. I received excellent instruction there. One of the smartest (and I mean really, really smart) people I know went to the same community college. Now we are both at a university. Both of us are doing well. You're smart enough. You can manage your time well if you start your assignments as soon as you get them. Rarely is an assignment so "big" that it cannot be done in the allotted time if you just start when you should. I think most colleges and universities have some sort of writing center where you can get help with writing assignments. Few people are excellent at everything so there is no shame if your writing is weaker than your other abilities. Professors use every day language; when they use jargon that is relevant to the subject, it's usually defined in the text or if in doubt: Google it! Some professors are jerks, but many are nice people who really appreciate the interested student. Go for it if you want to! You could start small with one class. That is what I did.
