Please help ME im going insane!?

I have been going out ith my girl for almost four years now. I am 20 and she is 19. We are both very loving mature fun people. When are together we are amazing and we know that special feeling we get when were together.

Things were a little rocky in the past. We cleared those problems up. We were amazing untill recently she got into a car accident. She was fine thank god but she now never has any free time. Work School Chiropractor Lawyer. She is always loaded with things. We dont even have any free time any more. this is killing me. We cant even talk on the phone much.

She is getting mad at me. I try to call her through the day and try not to get her mad. She calls me when she can sometimes. SOME days she dont even bother to call me. I try and keep in my head that she is just so over worked and has to deal with people all day that maybe she dont feel the need to talk to me. I would feel the need much more as i have more free time. HELP
