It seems you have your answer – you can return in 2 years and finish your degree. And that is something you do – even if you take one course at a time while you are working. And you know that med school is not an option given your grades. So it comes down to what should your next step be. IMO it makes sense to work for a while, clear your head and mature to a point where you understand the effort that has to go into finishing school. I like the suggestion above about getting your EMT training and doing – it could lead to a nice career in a medically related field.
