Swollen Feet & Tingling in fingers

Hello, we are almost 23 weeks with our baby girl and my feet and ankles swell up to balloons EVERY DAY. No matter what I am doing they are swollen. My doctor seems a bit concerned about it and told me I need to take it easy, but that's not exactly an option. I work two jobs as a CNA and a nanny as well as go to school almost full time and I am a wife and fur mom. By the time I get to sit at night it's almost time for bed. Not only that, my fingers and arms have been going numb and tingly. I don't know what to do, why are my arms and hands going numb and what can I do to help with the swelling, what happens if I can't find time to sit and relax, what could happen? My doctor told me he needed to see me in three instead of six weeks so I'm a little worried I just really don't know what to do or how to relax.
