I agree with picking a trade. If welding interests you take the steps necessary, even if it means going elsewhere. Long term, you'll be much happier.
Also, if the crippling debt obtaining a college degree might leave you with worries you I might suggest seeking certifications in whatever field you choose. Some of my friends did this and are doing very well without the traditional 4 year degree.
Find what you want to do and what certifications you need, then pursue them. Best of luck man. Truly.
