Depressed?

I don't know what depression is but I do know sometimes I feel completely alone even if I have my SO next to me lately I've been feeling like this more often and I don't know how to explain to him because I know he's stressed out about work and money. I can lay in bed and cry and an hour before he comes home I take a hot shower and say my face and nose is only red from exfoliating. He'll hold me and say you know I love you and I'm here for you... I know he knows I cry but I know he doesn't know what to do either but I'm crying right now about to hop into shower and "exfoliate" my face...😔
