Salley I have no idea about the medical resources in Gambia. You need to see an Eye MD ophthalmologist that does eye muscle surgery (strabismus). At your age the only thing that will likely help will be crossed eye (esotrophia) surgery. If there is a medical school in the country they may have such a surgeon.

I understand how you feel. I had crossed eyes also
when I was younger but I had surgery and now
my eyes are near perfect - nobody notices anything
now. I dont know if that is an option for you but it
helped me greatly. My surgery was done in Durham,
NC at Duke Eye Center.
