Everyday Seems A Struggle With My In Law

I am always a energetic and smiling person who thinks positively . but if she is around , my Face turns to a serious one and I dont feel like being myself ..
I change to a completely different person when she is around .. Anyone like me. how to change this

 

Your mil and mine are sisters. can you tell me how you created drama .. can u tell what all u did.that would help me so much

 

I tried this for more than three years . This technique did not stop her from shouting . moreover she knows that even if I go to another room and lock , I can hear the shouting . so she screams even more .
two days back , she was talking to me harshly . I replied to her questions and then walked out saying that you are screaming all time .
after that incident , she was behaving well until next day. again today little bit she has started .
I want to keep a complete full stop to her stupid behaviour

 

I also complained to my hubby about her behaviour as she might complaim to him about me . I told him that she is screaming most time when I am in front of her .
his reply was in one word 'ignore'
mine was love marriage . he was my best friend . though we loved and knew him for 6 years before marriage , I never knew that he will be this heartless , brainless, spineless .
I don't feel like loving him anymore . I am not asking him to fight for me . but how can he easily say ignore and then mind his own business

 

She shouts at me if I cut apple for kid and keep half of apple without eating . but today I saw half apple which was cut . it had turned black . happily she is standing in front of that Apple and doing work . if I had cut it , she would have screamed .
their place is too hot . she screams if I don't switch off fan in hall. even if I go to kitchen for 2 mins , I need to switch off. else she Ll scream. today she had not switched off fan in bedroom and was watching TV . when I asked her if I should switch off she said cooly ya
I want to tell her ' see if I do same things ,think how you ll scream at me '
should I ignore her or react to her .
I never stood up for myself . last year she had come for 5 days to my house and was doing ragging . I did not have much courage to tell her .
this time , I am openly showing discomfort and showing faces and raising voice ( still not much)
my sil was telling that her grandmother was too strict and brought up children nicely . for which I replied that her grandmother was aggressive and that is why all children whom she brought up are arrogant and aggressive .
I am not cooking now in this vacation for 2 reasons
kitchen is place where she shouts too much
my kid is too naughty . so I can't leave her alone .
definitely she Ll complain about that
I want to tell that as long as she screams , I Ll not stand next to her in kitchen . how to tell that decently

 

As you all said I need to move out when she shouts .. but she shouts all time . how to move out in that case.

 

I stayed with my mil for 20 days recently and she did not shout at me much ... I avoided her as much as I could by not being in same room as her ...
I don't know reason y she did not shout this time in front of hubby .. Last time when I stayed I openly told her ' you are screaming at me all the time'....
Do you girls think she might have changed or is she acting as wants to be in joint family
