If you are sick and suffering then before you go to your Doctor, stop, retreat within and examine yourself as to whether you have ever -

blamed Almighty God for any reason whatsoever

hurt your parents, members of your family, friends and neighbours,

killed anyone,

committed adultery,

stolen things of others,

given false witness against your friends, neighbours or anyone,

felt jealous of belongings of others,

insulted others.

If YES repent for your misdeeds, faults, forgive others, offer your worries to Almighty God and pledge not to commit the same mistake again. I hope you will be filled with peace in your heart and that peace will heal you from within.
