Holy vitamin D aside, summer is a very depressing time for those who suffer from loneliness. I just went out shopping to buy food and I saw tons and tons of happy people on the terraces having drinks, couples strolling naively and loving each other with pure love. And there was me, alone and contemplative in front of this mass of happy people that I envy.
Oh god, I wish I was a normie and had enough social skills to make activities with friends.
