At 38 your young to have heart or circulatory problems but from what you describe you may need to see a Cardiologist to rule out any circulatory problems. I would at a minimum suggest having blood work with differential to show any other possible cause's. This is not a depressive symptom but a biological one in nature and you need to see a doctor for a good work up on this. I would also speak to someone on the depression issues as there are many good mediations to help.
Go to a Cardiologist or your primary to get this started. It is not a dermatological problem.
If I may be of further assistance please reply.
