You sound depressed, I think it takes one to know one. Working at Google in the US is a dream 99% of the world can only dream of make sure you value it.
Also as others have said, don’t expect that your job will fulfil you completely, unless you’re curing cancer it’s just a job, talk to your manager about a different role or a bigger challenge but don’t give up a job at Google because you’re bored.
And get some counselling, it’ll be the best thing you did in 3-6 months.
What people dream about doesn't really mean anything. They don't actually live and work at google, as a software engineer. They just see some kind of marketing version of "a day in the life of a software engineer at google". It has nothing to do with reality.
Every programmer I met is depressed, hates computers, and spends all of their day just pretending to work because they burned out in the first month of programming. Programming isn't a real job for actual humans. We can't do it. The market just demands it.
