Dear Aurora
there is no such thing as a second-class jew. Or as the Lubavicher Rabbi (Chabad) said it, there are jews who do mitzvot (commandments), jews who do more mitzvot, jews who do even more mitzvot. You should keep that in mind, whatever you decide to do in the future.
I think you should focus on finding a jewish spouse. I know it is difficult in a place which does not have a big community and most people are reform / conservative / unaffiliated. But if you think fast forward 30 years, this will have enormous impact on your life and shape your future.
Have you thought of asking someone to come and help you and kasher your kitchen?
It’s very hard to give advice about shabbos without knowing you and what you find difficult, but perhaps you can post questions, many people try to answer and give different viewpoints and suggestions, hopefully you will be able to find some little piece of advice that suits you.
