Switching keyboard layouts is really hard it can take a lot of time to adjust. I haven't been using it for very long (only like a year and a half) but there are lots of users who say it is well worth it in the long run. If you're feeling f-ed about your new layout, I recommend trying to learn it as a side project over time, rather than making your whole setup use it. Stick with what you know for important stuff and use something like colemak academy until you are proficient enough to make the switch.
