AITA for going off on my sister after her weird behavior

So for the last couple years my sister has been behaving in a way that is now causing me anxiety every time I visit her (Currently writing this in my bed because I lost sleep over this).

It all started when I started college a few years ago and got admitted to one of my university of choice, but all she could say was if I am 100% sure and was trying to plant doubt/discourage me .
The next time was when I got a boyfriend (ex) and started to obsess about how he treats me, He was a generous man and the guy she is STILL seeing do 50/50 with her. and then she would act so strangely like behind closed doors she portrayed him as this bad man and how I MUST break up with him but whenever she met him personally she would turn into a sweetheart with him.

Another time was when I started living abroad and then she became obsessed with moving and living with me (which I was open to in the beginning) but then every time she visited me she would go through ALL my stuff /closets. then she makes me feel like the bad person for getting upset because she was just trying to "help me tidy up" .

Right after , I got laid off from my dream job abroad and was considering moving back home . she then REALLY became obsessed with moving in the same city i did and was enrolling for similar courses. when i told her that I am actually considering going back home and it is not possible for her to move with me anymore , she was like "go ahead , I just want to try to live there too I am free to do what I want".

I lost weight at some point and did some shaping , her first reaction was " you will gain the weight right back"

She went out once with a guy who told her he got arrested because he was driving drunk after a date to which I commented that "he seems reckless " then she had the nerve to Tell ME back " Yeah , just like you right " WTF.

I was once trying to joke with her about how cute she looked (she is 10 years older but on the shorter side) and that I wish I was her older sister so I can coddle her sometimes , she then gave me this weird very weird comment "yeah , then I would have had your personality and you would have ended up with mine "or something more like " I would have been born you".

I started a new work venture , 6 months later she quite her job (sabotaged herself so bad she got fired) and applied for similar positions in same country and then when I tried to confront her about IT , she made me look like I am obsessed with her ?

I planned a trip for myself recently and was so excited about it. then I visit her and told her how expensive everything was with the flights and such. and she has this facial expression like "wow you are so rich now" I AM NOT. and it seems she doesn't like it when I am adventurous . For the first time I wanted to grab a travel size shampoo from the grocery and then she follows me in and started grabbing stuffs from the shelfs and then she was like "could you pay for them ?"

Am I going crazy ?
