Dear Sparkly,
First of all, let me tell you that it is really inspiring to hear of a fellow Jew who wants to become more religious. Yaisher Koach!
I completely understand what you are saying about Shabbos and Kashrus. When I was first becoming frum I was told the same thing in Ohr Sameach. There is no proof available. It’s assur to publish this type of psak Halacha because it can so easily be twisted or misunderstood.
As you can see, most people here in the CR do not know you and don’t understand your perspective. It can be very hard for an FFB to understand a BT and vice-versa. Please don’t be insulted by the misunderstandings.
I am going to guess that what you meant by “more religious” in your OP was something along the lines of “how do I develop a relationship with G-d?” If so, then I would say absan is correct, you need to try to find a teacher. It also helps to develop relationships with other people who want to become more religious. Even if you can’t do that right now, it is O.K. to just say “when I get the opportunity to grow, I will try”.
Good luck and remember there are a lot of people who are proud of you!
