Sometimes regret keeps us from moving forward if we don't take advantage of the opportunities in front of us now, if we spend too much time dwelling on the past. If you have the chance to pursue your dreams, go for it!
It is quite a number of credits before running through financial aid; talk to your fin aid office to find out what the current number of max credits are for a bachelor's that fin aid will allow to help you in your determination as to how far you can go with their assistance. It may be just enough to get you through. There also may be more scholarships and grants available to you now being in a different age category as well; this is the good news too, look at age as a positive, not a hindrance.
I wish you well as you move forward and know the only thing stopping you is you. Good luck!
