I'm going to lose my job

I work for a hospital system, and they don't know what to do with me. I've been in 2 different positions in 5 years. I don't want to be too detailed just in case someone here works for the same system. I don't work inpatient, it's more niche than that. It's finally come to a head that I'm not busy enough. This is something I've known and have asked for more work. Since they didn't know what to do, nothing came off it. I now have to prove my worth in 3 months or I'm gone. I have a couple of interviews set up, and have worked part time for a group practice that said I could come in full time. I feel stuck and that no decision I'm going to make is going to be the "right" decision. Just looking for help in processing my thoughts and feelings.
