feeling insecure

hello ladies, how do y'all do it to feel good about yourselves? lately I been feeling really insecure about my appearance. I don't really get my hair done, neither make up or anything like that. my husban says he doesn't care, I always tell him that his friends girls are always dressed up and look nice and I don't, and I can't help to feel that I could do better, I just don't know how or what to do. I have a one year old daughter and about 4 months ago 8 I had a miscarriage and I always use that as my excuse. any recommendations??? I want to feel good. Thanks for reading :)
