My new job makes me so sick I can’t get out of bed on the weekends and throw up every night.

The long hours and one lunch break is so hard on my body but I have no other job options at the moment. I have several medical conditions that I need to eat, drink and move my body at certain times of the day. Sitting at the computer for 9 hours all day t-s triggers my medical conditions. I just graduated from college so I should be able to do a normal job but physically can’t anymore 😞. Any suggestions please! I can’t afford to quit at least till I find something else.
