Will 2018 be the year I go back to work and feel worthy?

Hi, I am a female rat born 14 february 1972. I have not worked for years due to ill health and becoming a single mother.
I am a volunteer at my child's school (Reception & Nursery), her ex pre-school (Trustee) and our local church (Children Play Sessions and Sunday School).
My child will be five years old and I will be 46 years old beginning of 2018. Will my health improve (I am having an operation beginning of 2018) and will I get a job in 2018?
I am petrified at remaining unfit for work for the rest of my life! I feel unworthy.
Thank you.
