I'm in a similar situation, except I have a 12 years of experience, but just an AAS degree. There are some positions that I feel I could do, especially in the plastic product design area, but they require a ME or other higher degree. There is a place for everyone. You and I just need to find that place.
If you want, send your resume to me, and I'll review it. I do tend to have a knack for resume writing. I've gotten many compliments on mine, and others I have helped friends write. sent it to d_e_sloop at hotmail.com (replace "at" with the @ symbol of course)
Like PSE said, network. Let everyone know your'e looking. So far, I have gotten leads from 2 mothers at my daughters daycare, 2 sales reps I worked with in my previous job, the VAR for my CAD system, and a couple from articles in our countys business development magazine.
I've had one interview in 2 weeks though, which is kindof discouraging. It is a position that I could do, but not really what I WANT to do.
Anyway, good luck, and search this forum for a lot of good advice. It's a treasure trove of info.
