I Wasted A Year Of My Career Working In An MNC That Promoted ‘Flattery’ Instead Of Hard Work

Hello all, I'm not writing this post to gain some sympathy but want some suggestions as to where I should head now.
A few years back, I came down to Bangalore from my native place, in search of a job. Within the next three months of search, I got a job offer at an MNC. I was feeling at cloud nine, though it was a contractual job. Initially, I was a bit scared about the new office environment and culture. But after I joined, I felt that I had the best team and there was no sign of office politics. Little did I know that there was something being cooked behind my back.
Most of the time, my reviews were negative and I was constantly told that I need to improve.
I always gave my best yet I had to listen to the crap from someone else. I found that the ones who joined after me were well-versed in flattering people and gossip and thus, they got more weightage. I was a quiet and an introvert girl, so I hardly raised any matter related to it. Soon some juniors got promoted, I didn't argue over it. Later on, everyone started to take me for granted. I used to be a backup for every other person. But for some time, I got some good friends on the team, who tried to cheer me up and guide me.
When they moved out, I again felt lonely, and things were going as usual.
I was longing for leave but first I have to confirm that no other person is taking leave at that time, which was a hilarious thing, as my team was a big one. Soon, I was suffering from some health issues which erupted because of work-life imbalance, and I took leave for a few weeks. I joined back and was working as usual. After a few months, some members moved out of the team, and there were some new recruits on the team. Again, entire pressure came on me to work on end-to-end of the process. I wasn't allowed any personal leave and had to work in extreme shifts. Even after that, I was always told that I wasn't working properly.
I was out of my mind and decided to quit the company.
Post that, I started searching job but was shocked to know that the profile on which I had been working for so long, hardly has any market value. Most of the companies don't recognize that to be proper work for which one should be paid. I have already lost a year on it. Now I'm in a dilemma as what I shall be doing next. Any suggestions, please?
