This is a difficult situation for anyone with a chronic physical illness that can effect there ability to chase dreams and set up goals and dead lines.
I think first and foremost you need to focus on feeling better physically, you need self care to calm your body and you need food to nourish it. Stress as you know is one of the biggest triggers for Lupus. So holidays and mom and work and all the other 16,984 things your mind was going through has taken its toll..
I am so sorry you are feeling this way. Try to not focus on things you just cant do right now, put your focus on calming your body which in turn will calm your mind.
Don't beat yourself up, get back on track eating well, Doing your yoga will probably make you feel better , just go slow , Don't push your body to extremes right now. Self care now will allow the imflamation to lessen which will bring "you" back in balance.
I'm sorry and know that I am here for you
