You medication regimen looks like mine..yikes. I take 16-18 medications/day!!
Oluwa has given you excellent advice about your Father, exercising, seeing your doctor, and your medication regimen. There is nothing worse than having a family member (who does not understand this disease) try to be the expert on what we need to do to manage this disease.
While some form of regular exercise is recommended for people with Lupus, it is always with the caveat: DO NOT DO MORE THAN YOUR BODY TELLS YOU TO DO!!!! Overdoing can indeed cause a flare-up, can cause new symptoms to appear, and can make current symptoms worse!
Perhaps you can try non-strenuous exercises such as yoga, pilates, or swimming. Until your father avails himself of knowledge about Lupus and how it affects you personally, you may have to request that he keep his comments, opinions, etc. to himself. It is very, very important that you keep your stress levels down also as stress can be very detrimental to this disease. Educating your father may help in that arena if he is willing to learn and willing to be supportive rather than demanding.
I wish you the very best, please keep us posted on how you are doing.
Peace and Blessings
Look For The Good and Praise It!
