He has hepatitis C?

I love him, but I am so concerned for him I don't have any clue what to do, he has no medical. We are working to get that, but in the meantime, how can I help? I am always so freaked out that his eyes and skin might be yellow, or whatever else that runs through my mind. there is no way in Hell I will leave him because of this, but what can I do to help him live with this disease, you know , like diets or exercise what do I watch for what should I be concerned about. thank you.

It was a dirty tattoo needle

He has it, and don't ever think about not going to a doctor because of no insurance. A lot of hospitals have doctors affiliated with them and you can get help paying the bills through them. Sometimes they will even cover the whole bill. Look into it!

Well, there must be some clues, as you said, for being engaged with these types of diseases. For example having blood transfusion, several unsafe sexual contacts or being IV drug user. If your sure about him, all your suspections are inconsiderable.
I think you'd better share this idea with him rather than to others and kindly ask him to have blood test for hepatitis for your sake. However, there are bunch of other internal problems which result in yellow skin like gilbert disease or high betacarotenemia which are quite harmless.

He needs to get his *** to a doctor and you need to stay away until it is all gone.

Have you only just found out?
Hepatitis refers to the liver. So, it's essential that he keeps his liver healthy. Which unfortunately means no alcohol or drugs, these all affect the liver.
Processed and fatty food does also.
A healthy diet, exercise and minimal stress would be beneficial for him.
It may sound a bit silly, but learning tools like mediatation, yoga and/or 'switching off' will contibute to an overall sense of control, which can be very empowering.
maybe you could go to some yoga/meditation schools together.
Alternative Medicine is another option.
Acupuncture can help in alleviating stress, a nutritionist can help you with what you should ingest, so will a Chinese doctor.
I have cared for patients that have had Hepatitis C for 10 years, and they are fine!
Bloods normal, and looking healthy.
Educating yourself about the disease is paramount for achieving realistic outcomes. Go to the local library or Hospital.
I don't know about the US, but in Australia we have clinics for Hepatitis and pamphlets for patients, or anyone wanting to learn about Hepatitis.
Education is vital with any condition, it gives the pt more control over their condition, which in turn alleviates stress, and promotes better well being.
I urge you if possible to seek a reputable Chinese Doctor, or Chinese Acupuncturist. There are other options besides Western Medicine, or in conjunction with.
As for you, being a great mate, confidant, and lover is the best thing you can do.
By the way your chances of getting Hepatitis C from having sex are very small. It's possible, but highly unlikely!
