It's pretty astonishing to me you could get that far in education and still wonder what you're going to do with your life but if it were me I'd become a principle researcher someplace. Public private wouldn't matter as long as as I was doing research I was interested in. Would never want to be a doctor, nasty people all day, plus you wasted 6 years. Hate lawyers in general they are unproductive bottom feeders.
This.
OP, I don't mean to be rude or crude, but there is a saying out there that goes "It is time to shit or get off the pot." I think that statement applies to your current predicament. I don't know why on earth anyone would waste time with a PhD in engineering if they didn't intend on doing research or teaching and after that investment (and, I assume, significant debt), it is time to get a real job. At one time, I had considered doing a PhD in engineering but when I was working in the Master's program, I realized that research was not something I enjoyed.
At any rate, don't be a career student -- they're a joke. One of my wife's friends dated this guy for a short time and he is in his mid 30s and has never had a real job to my knowledge. He keeps wasting time going back to school for various reasons and I'm not entirely sure if he has ever completed anything beyond his initial Bachelor's degree. She acts like he is really smart, but come on -- the guy was in his mid-30s and working menial jobs. He is a directionless buffoon and at some point, you just need to set course and never look back.
