I just want to take my baby n leave😥 (long rant)

Before I got pregnant I was never an emotional or sensitive person but now that my lo is here I can't help it but I kno I am not being overly sensitive now. Before my pregnancy I would smoke cigarettes but was able to stop during my pregnancy. I picked up the habit after my baby girl was a month, currently 3months now, bc I was suffering from depression. My husband n I rent a room from his parents for the time being n plan on moving soon. The first month his family especially his mother was causing me so much anxiety that I had to get away for a bit so I stayed with my parents for two weeks. Ever since than I have beginning to hate his family. His mother has been brainwashing his sisters to believe I am not doing right by my daughter bc I smoke n breastfeed but research has shown its best to breastfeed than to give formula if the mother smokes n I even confirmed with my daughter's pedestrian bout it n she says that my daughter is doing excellent weight n brain  wise development wise. Recently his mother has said that my daughter is fussy some nights bc she is addicted to nicotine bc of me, my breastmilk is water, n that I am neglecting my daughter by not giving her formula. I am pissed bc she is running around telling his sisters this bs as well. I picked smoking back up bc of my anxiety n depression n saying that I am a bad mother or that I am not doing right by my daughter doesn't help. So today I just came back to the house from another getaway to my parents house n luckily wen I got here his family wasn't home. My husband knows how I feel n we talked again today bc I told him that I don't feel comfortable with his parents seeing our daughter tonight n i thought he would respect it but nope. He brought me up a plate of food n asked to hold our daughter so that I can finally eat n he quickly says I am going downstairs n takes our daughter with him to see them. I was livid. Like damn give me one night like how I asked or even talk to me bout it before leaving the room so quickly. I am so hurt by him n his family bc of this bs. I am a ftm n I take care of my daughter every second of the day with no help from anyone with maybe 2-3hrs of sleep. I do the best that I can by my daughter but smoking helps me. I smoke 2-3hrs after a feeding or pump session since it takes about 95min for half of it to leave ur system, I don't smoke anywhere near her, I change my clothes after I smoke just to be cautious. I honestly don't kno how to feel or wat to even do anymore bc now I hate his family n I am starting to hate him as well😥
