What is your degree in? Do you have any marketable skills? First think about what you can do, than try to find something to do. I wouldn't be waiting tables, etc if I could do something else.
To be honest, you don't have any guarantee that you're going anywhere in 12 months time, so I wouldn't be sharing that with anyone. You may find that many people will not be happy about your going to medical school, and I don't just mean your employer who will have to find someone else. There's a lot of jealousy of success going around. My wife doesn't tell random people or clients that I am a physician if asked. She says that I am "retired military" and that usually covers it. Sometimes she adds that I do some contract work for the hospital. Both are pretty much the truth. She absolutely has been treated differently when people found out what I do. She also doesn't invite coworkers or clients to our home for meetings, etc. Be careful with your information, it could cost you a good job.
