Just found out i have seasonal affective disorder, what to do?

SAD, depression: Consult with a psychiatrist or mental health professional to make sure that's what you have, unless they diagnosed it. They might have additional suggestions and treatments. You can look at this or other websites as well: http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0002499/.

SAD: Treating seasonal affective disorder: Consider a tropical vacation when it is cold back home. Light therapy can be very effective. Psychotherapy and psychotropic medications can also be beneficial. See: http://www.mayoclinic.org/diseases-conditions/seasonal-affective-disorder/basics/treatment/con-20021047
