Hair, skin and anxiety problems. What to do?

I'm 28 and was on Antibiotics for years to control my acne. Over the years I have seen a flurry of skin and hair issues including seborrhoea, acne, hair loss, premature grey hair, keratosis Polaris etc. In addition I've had anxiety, fatigue and depression.

It seems like they are all tied together.

I have read so much about certain cleanses, foods, supplements and the information is great but overwhelming.

Can anyone please help me in what direction for treatment I can take? Thanks!
