I am 24 , 5'3ft 90kg and done with life

I am a Coperate Mazdoor, last year I gained 10kg and In COVID I gained 15kg Now my total weight is 90kg.

It's killing me each day, From gym to diet plans I have tried everything but my comfort food habit is not letting me do anything.

Also I cant even workout daily due to lack of discipline and Working hours.

I don't know what to write but I am ready to buy any medicine or suppliment which can loose my weight in 3 months
