There are quite a few videos on You Tube showing bike fitting.
https://www.google.com/search?q=you+...a&channel=fflb I'd suggest watching a few of them to get a better idea of what to look for and or measure to get your bike comfortable. Some aspects of bike fit are counter-intuitive which make them difficult to evaluate if not aware of them.
I don't know if you may or may not have the right size bike. Either way, stay with it and you will arrive at a comfortable bike in time.
