I have worked at a hospital for almost 15 years and now I am in a low paying job.. single mother and about to be evicted and lose my vehicle. I need financial help bad... please help. How can I find out what I can get out of my 401k from the hospital?

Ask your supervisor there. Some allow for a loan to be taken so you can use the money without paying a penalty. Most of what you can do is outlined by the plan and its administrator.

If you still work at the hospital, you can't withdraw money but you can get a loan from it
