I am afraid that one day all these anoying health problems will escalate faster than I can deal with them and I will become my mother.

Mum is sick, dangerously overwieght, isolated and lives alone.
Most of her family are gone. her husband has passed

She worked a physically hard job to make a life for her familly. Raise them provide a home, education and yet at the end of it she is alone.

Not her fault. Just happened that way.

Isnt facing your fear the first step?
