Hi Valentino, welcome to the forum! First, sorry about all what you went through. Your story is very familiar, most Hepatitis C sufferers go through the same down spiral. Hepatitis C is a terrible virus that is capable of turning people's lives upside down. The good news is that it's now curable as you know, the new DAA medications eliminate the virus with 95% success rate on the first try. As a matter of fact, almost all people say after just 1 week of treatment that they haven't felt this good in years.
Hepatitis C symptoms (such as fatigue, mental fog and skin rash) definitely go away after successful treatment. The only symptom that I'm not sure if it's related to Hepatitis C or not is hair loss. Dr Freeman who is a Hepatitis C expert and who founded FixHepC answers all questions posed here, I'm sure he will let you know.
Hopefully you will start treatment and get your life back very soon, best of luck to you and keep us updated.
