Before you do anything, make an appointment with a local flight surgeon and get a first class medical. That, in and of itself, will determine if you can go any further.
Next, get a two year degree from any junior college keeping in mind that you'll need to transfer any credits over to the University of your choice. That will probably save you 30k or so. If you're panning to go to Embry Riddle in Daytona, I HIGHLY reccomend looking into Floida State College @ Jacksonville to get the 2 year under your belt. They have a pilot program where ALL the credits will transfer over to ERAU. Their pilot courses will allow you to use your GI Bill to get your license.
Also, if you can pull it off, buy a nice IFR equipped Cessna 150/152 to build time in. They can be had for around 15k now. You can lease the plane to a local flight school to offset the maintenance. Then sell it after you get your IFR ticket and get some of you $ back. During your initial phases of flight training, it's more important to build time than it is to go fast. You can save a TON of money on fuel by flying everywhere you go as slow as possible. Seems counterintuitive but hours and ratings are what they look for. An hour in a Cessna doing 40knots is the same as an hour in a Gulstream doing 600knots.
I considered the professional pilot route for quite some time but opted out when I did the math. If you peruse it, you better LOVE it because you could be a doctor or lawyer for the amount of money you're going to invest in your training. When you start working the small carriers, you're going to be making near poverty level money till you advance. And...your entire career is dependent of maintaining that medical certificate. If you lose it, you're back to delivering pizza. If you love what you do, however, you never work a day in your life.
