To lose a loved one at any time is one of cruelest things in life to endure. Yes, I have lost several loved ones during my 25 years with Myasthenia Gravis and the stress will make some symptoms worse.

However; I feel it much harder for your physical body to cope if you do not allow yourself to grieve properly. To hold all those emotions inside will only make your physical body ill & may manifest itself as an exacerbation regardless.

Allow yourself to grieve fully for the loss of your beloved brother and if you feel your myasthenia gravis exacerbating; call your neurologist. Sometimes during times of stress, people with autoimmune diseases can be given what is called "stress doses" of steroids to help the body cope.

I am truly sorry for your loss and hope that every wonderful memory of you your brother will be forever cherished.
