Why can’t I leave the house

I leave the house to go to work, I can leave to bring my daughter places

But, she goes to her dads house so when she’s there and I’m off work,

I can’t leave. I could have a whole day to myself and all I can do is lay in bed. I can hardly even get myself to take the dog out it feels like a huge task. I think its depression but it’s like I WANT to go out and do things I just feel stuck in my bed. And it’s weird that I have no issue with it when I have to like work etc but

Going to the store, or anything fun, I just can’t fucking get myself to get out of bed on my days off if I don’t have my daughter.

I’m rotting my life away
