I feel that my cat has depression? Can someone help me?

I don't know what to do. I suffer from depression. I'm in and out of it. Now I'm in a depression. My cat sometimes looks like me. Lays in bed all day with her eyes open. She started just last week to go into the corner behind the night table and lay there or sleep there. I covered it with a pillow since I didn't need it anymore. I saw her try to go into that corner again yesterday. She meows alot and makes noises. She started a nasty fight with her mother the other day. Sometimes though I think shes ok, she comes out of the bedroom and wonders around but for the most part shes in there. Or in another corner in like this storage cage I have in the living room. She wasn't going in there in like a month than she started again. I just got them a toy she played with it the first day and now she doesn't want to play with it again. I thought if she had a toy when I don't play with her and it works on its own she be better?? I always check to make sure shes breathing I am very worried about her. I kiss her and hold her every single day. I give her love every single day. SHe also wasn't eating her wet food anymore for like 2 weeks. Every other day I give them that. So I didn't the other day and gave them today. Its gone they both ate the wet food. She ate the food, so I really don't know whats goin on?? Is she depressed or not?
