Struggling to Find Joy in Life

Figured I'd see if anyone else experiences the lack of enjoyment in overall life. I just feel like it's too long of a wait period till it's over. I'm not suicidal like I used to be in my younger years. Mostly because I'm a single mom and this kiddo relies on me and I wouldn't dare let anyone else take care of him. I show excitement around him while doing things but deep down I'm just exhausted. I can't only be around friends for a short time and here and there because it just wipes me out. Just listening to them talk about things is draining. Anyone else feel like this or anything that helped you feel happy for real? I honestly just think it's my personality...
