Need prayers and advice

Hello. I'm a 24 year old widow. My husband passed in March on the same day I have birth to our second baby. I'm living with my parents because I didn't and still don't want to be alone. The problem is I feel useless sometimes. I don't work. I do have a good income and support my children on my own. I don't take my parents money for that. I cover all my bills and my childrens needs. I do not but my own food but I do all the cooking and cleaning so my parents are ok with that. I just feel like I should be doing more. But if I work I may lose some of the reliable income I have now. (It isn't welfare) my oldest is 4 so he is in school so I just sit here with my 8 month old everyday. I'm lonley alot and extremely bored. I just feel like I'm not doing enough or I'm not good enough. It's hard to sit here everyday alone. All my "friends" quit me when I got married and had a baby at 19 so it just difficult. I have no one to talk to. Of course I mean in God everyday and I know he will take care of me but I'm human and still start feeling down. Then I feel bad for feeling like that because I do trust God to take care of me. What should I do? Should I feel bad for not working? Like I said I do all the cooking and cleaning here and also take care of my boys of course I just don't know.
