Stuck in grief

Over the last 10 years, I have lost my teenage son, my sister to cancer, my brother to accidental overdose, my other brother to a heart attack. Most recently, I was a caregiver to my mother for several years before she died of Lewy Body Parkinson’s disease last April. My last remaining immediate family member, my father, was diagnosed with Lung cancer when my mother died. He is thankfully recovering. I have lost a decade of my life. I wish to get my holistic work business going again, but I keep getting stuck with thoughts of grief. These thoughts tell me it’s too late at 57 years old to reinvent myself. I have the desire to do it though.
