Inshalla, bro. Things will get better for you. Pray to Allah for help, the treatments will alleviate the pains and problems.
The disease is more prevalent in places like Norway. The version that you have is carried by people between 12-15%.
I found one study that represented Oromo and Amhara samples classified as
Central Ethiopians, and for a separate mutation in the HFE gene that causes hemochromatosis named Cys282Tyr, they got zero frequency:

While the one you carry was different in that they had elevated values (Oromos and Amharas, that is):

This mutation called His63Asp is essentially the same as the one you called H63D. That mutation, as you will notice, has 9.4% frequencies among Oromo and Amharas. Basically in heterozygous conditions, similar to you. It has a 1.1% homozygous condition which usually leads to more potential for increased cases of iron build-up. The value appears higher than Mozabites who are Berber (though they had no homozygous conditions, which could be because they had half the sample size compared to the Ethiopians. Or maybe not).
It seems like Cys282Tyr (C282Y) is strongly tied to the Celtic and Viking disease, while H63D is much older and is less associated, but is in a weaker sense, associated with iron buildup without necessarily a full-blown clinical hemochromatosis. However, it can cause the symptoms you mentioned, with other health issues.
Did your doctor say you had hemochromatosis or just iron buildup and liver problems?
We see 8.3% of Oromo and Amhara got one copy of H63D while 1.1% had both alleles as GG which means those people could be more susceptible to having stronger symptoms, despite it having nothing to do with Celts, at least, directly.
In another study, it shows that H63D is ~15.17% in Tunisia with ~0.09% for C282Y. In Egypt, you had ~20% for H63D, with no cases for C282Y. For Moroccans, this went up to 27% and 0.9% heterozygotes and homozygotes of H63D, respectively.
H63D is not as uncommon as one had assumed outside Europe. Rationally speaking, the way it does not appear among Senegalese, I would think this was introduced through the Eurasian side. Yet, we see no cases of C282Y among the Ethiopians, pointing out that this one is more European-related. Tunisians and Moroccans who barely had any, received European gene flow from Iberia, during pre-history, down to well within the Common Era period through diversified and lesser frequency via the Mediterranean.
