purple pen

Hi, I graduated 5 years ago from a large school. I tried asking professors for recommendations and all I got was "I don't remember you, I have way too many students to keep track of." I tried going through the Career Center, but they only hold letters for students written by professors. I was going to ask my employers, but I'm on a new job, and my old job has nothing to do with the field I'm going into. I'm running out of time and more then stressed. Any advice? I'm applying for joint degree program and need 3 for each.
