Hi Sabari,
It may help to take a look at how/where your left hand is placed while making chords. I initially had a lot of problems with barre chords because my left wrist (for me) needed to be further “under” the neck rather than “behind” and a bit “forward” as well
Go back, watch the video and pay particular attention to the instructor’s left hand positions. It’ll be a bit different for every instructor but that may give you something to model as you find what suits you the best.
Hope that helps. Don’t get discouraged. Follow Christopher’s advice above and you’ll progress nicely.
