Long-Term Health Problem. Complexion).

Greetings Sir/Mam I have a problem which has lasted so many years that I am afraid now that it is not too late. I have no idea about which disease I am suffering from. First, The nutrition part, no matter how much I eat my body structure never changes, same goes with weight. Secondly, Genetical Difference, all the members of my family are fair complexioned and healthy. I was supposed to be similar but unfortunately in my early days, due to some disease, I lost both the complexion and health. Due to this, My self confidence has become very low and I couldn't concentrate on studies or any other activities. For the record, Both my parents are suffering from diabetes. So, it is a sincere request from a concerned pateint to someone who can help me getting my health normal and complexion same as it was genetically determined (parents' complexion).
