dark skin

Dear Father, I'm losing weight due to multiple stressors. My appetite is very low and I look thinner, skin is very dark and I’m scared. Please help me rebound from this in Jesus name. My doctor is no help.

Week ago I woke up and had sudden dark patch under my one eye. Now it is slowly healing. I don't know the reason why it happened. Please pray I get clear skin under my eye and have no dark skin.
