Getting depressed

I know part of it is due to quarantine and I honestly feel like I'm just bitching saying this but I need to get it off my chest.

It's literally just me taking care of my baby and the fish tank. My mom was living with us but she is currently staying with my aunt. Her husband recently passed and she's physically disabled so she was having a hard time taking care of herself. Also I'm really glad my mom gets to help out and I even encouraged my mom when she presented the idea to me. But I can't go hardly anywhere or invite anyone over and as a result of that my son has become extremely attached to me! (Like glued to my side 24/7) I love it but it can be exhausting. My sleep has been horrible because I keep having nightmares and it keeps getting harder to put a smile on my face and entertain my baby all day.

Also I understand I'm not the only single parent out there and my situation is not unique right now this just helps me organize my thoughts
