Hi holdthetonic! You have the right to feel well, both in mind and body. If you had an infection, you would probably be prescribed antibiotics. If you're needing antidepressants they too have a place in your wellness arsenal. Imho start with a visit to your GP, call whatever sources ar available in your area, and treat yourself with love and respect. True depression is not something you can "snap out of". And tbh not all counsellors are created equal, so if one doesn't work, ask for another. Don't give up on yourself! 
Ps. Sad rainy wintery days don't help either!
