Anxiety & In laws.. in Life Lessons

So, if you have read any previous entry you are aware of my situation.
My mother in law and sister in law are absolute jerks to me.. I dread being around them so much to the point I make myself sick. They won’t say anything to my face but then they call my husband (while I’m sitting there listening) and cry about how I don’t want to be apart of them and don’t like them. They are pills to everyone they ate around (anyone I talk to about them has nothing nice to say). They never want to include me, never check on me when they know I’m sick, always try to tell me how to live my life (when to have kids and what to name them), always whining that we don’t come see them enough (we usually go see them at least once a month) all while they never come see us. I feel bad for my husband because him and his dad are close so I feel bad not letting them be together but I absolutely can’t stand my mother in law and sister in law. Part of why I dread having kids is because they will have to be involved. I just don’t know what to do.. my husband doesn’t like how they act but he doesn’t feel like saying anything will fix it.. he’s afraid it will only make matters worse..

My mom can also be a pill quite often… my husband isn’t a huge fan of her.. we got into an argument the other day because he doesn’t want her in the room when we have a kid but I probably will… recently my dad has been under a lot of stress - new job, bad health and caring for my grandpa 24/7. My husband thinks he is a lazy jerk because sometimes he doesn’t text him back or never tells him information that my husband needs to know, or that my husband needs to work harder, just little things that irritate him.
I don’t have any clue how to approach these situations or how I can fix them.. any advice is appreciated!

Currently unable to sleep from anxiety worrying about all this…
