It's OK to be depressed sometimes. Even starts can't shine without darkness.
Never think about your depression as about something personal, people everyday suffer because of it.
Try to enjoy it and cope with it with help of wine, friends, comedy movies, cute kittens and puppies, online games or medicine. I used to take some of these https://nootropicboost.com nootropics and they were OK. I can't say they destroyed my depression, but they helped me to cope with bad thoughts one day in the past. Now I deal with anxiety thanks to my german shepherd named Sammy.  She's adorable and she just doesn't me give time to be sad.
