Reality vs hope

So I recently changed my job (startup I was working for got closed). Got a decent hike the team is big than my previous org. But I'm not feeling the same excitement and enjoyment I used to get my prev org. Reason of not feeling good: Was working on more comfortable language org, but here try hand on new language. Was given time to discuss and then code thing in prev org, here just push things asap as it's business important. So planed that I will give 2 months time then decide I need to continue or not. After 2 months still in dilusion. Any thoughts that's is common or just over thinking.
