car wont start, has been running fine until this, wont shift out of park, yes I am pressing on the brake. Battery seems fine lights and radio work. Brake lights come on when brake is engaged.

Sounds like a bad ignition switch....

is there a way for me to figure out if it is the ignition switch? I am a single mom, but pretty savy about these things when i need to be. I dont even know how to get it towed since it wont come out of park, any suggestions?

The car can be towed, even stuck in park- use that part of your budget set aside for car expenses-
