Mother in law

So my husband and I have been married 3 1/2 years but best friends for 12. We also have a 2 and 4 year old both girls. We don't typically have any problems between us until his mom gets involved. She struggles with depression really bad and uses it as an excuse for everything but at the same doesn't really want to do anything about it. I'm not the type if person to baby people either. I'm considerate and will go out of my way to help others but she just takes it to far. I've always been a stay at home mom, I never do anything even to go to a friends house I usually have at least one kid its been over 3 years since I've been out with the one friend I have. I just recently went back to school and decided to deactive my fb account and my husband and my mother in law have been talking about me behind my back sense saying that I need to go get depression meds and that I'm not ment to be a sahm and that they pray I get better soon and they will pray for me. Honestly I'm tired of trying to talk to my husband about me needing something in my life for me or anything I want or hope to do because he always runs to his parents and weather he means to or not he makes me out to be a horrible person and his parents already don't like me because I'm out spoken and very independent. I'm so broken all I ever have to talk to are my 2 and 4 year old I take care of literally everything my husband doesn't even make his doctor appointments or remember when he has made plans. I don't feel bad for going back to school I just wish him and his parents would stop making me out to be a bad mom and wife.
