Do i have malaria or anxiety?

I got a mosquito bite on Sunday and its alreqdy starting worry me, I have been so scared which makes me think I have the disease, I haven't had a fevwr yet, or chills but its felt like I am sick thinking that I have a disease, and it convinces me that I do have one. I just want to get this off of my back, is this malaria or just anxiety"thinking I have malaria"?
