I am the same, it's why I want to work when my kids are with their dad, I sink into a dark hole and struggle to get out. Talking can help. Do you have a bath? A spa day pampering yourself, face mask, nails, hair, make up, favourite tunes, get dancing, go for a walk to the shop buy a magazine and a cake to have with a cuppa, plan cinema, few ideas, sometimes listening to radio makes me giggle. I'm thinking of doing meditation.
hope today is better
