I am afraid of changing job even though there is a high chance that the next job has better prospects compared to my current. Should i just quit or stay?

I would quit

Am stuck in the same situation as you

getting comfortable with where i am but also want to jump for better pay

gonna try throwing my resumes out and see how

What do you want?

Just go for interviews & wait for offers! Low stress is not necessary healthy (a little challenge activates the mind) unless you have a mental issue to manage (not trying to be offensive, just factually).

Salary & staff welfare is more of lousy benefit package, how about the culture and colleague relationship?
