I don't know how much longer I can work. What are my options?

I'm 16.1 weeks pregnant with twins and to make a long story short, my fiancé left me at around 10 weeks for the mother of his three month old. He doesn't communicate with me even when I try to reach out.

So now I'm stuck handling all of the bills here alone. I work at Starbucks and it is extremely busy all the time. It's hard to get a break or even water and sometimes I'm left alone in the store. I was sent to the ER during my physical for my new job because of different factors. This is my full time job. They said I can sign up for short term disability but it won't start until next year since u declined last year.

I just got hired as a receptionist for another company for mornings but this is only part time and won't meet my expenses.

My doctor suspects that I have lupus because I have had a lot of protein in my urine for a long time and will be further tested for it Monday.

Any advice?
