Spring seems to be a rough season for me emotionally

Nothing bad is really associated with spring for me, but it seems to be a time that I feel more prone to feeling loneliness or depression. Worse, it seems to be a period in which I respond to these things by withdrawing. There's that lonely feeling but also I just don't have the energy to interact with people. I start thinking of more things I want to do, but I lack the energy to do anything. And that's if I'm lucky enough to have the money or time to do it in the first place.

Why spring though? Isn't it usually winter that drags people down?
