Hi!!! Welcome to the forums
It is ok to want to go back to relaxing. Being natural isn't for everyone. I would say think long and hard about it. It will take you some trials and errors to find out what works best for your hair. It took me a little while to figure out, but I did. I would recommend washing more than once if you feel that it will help your hair. You just have to mix and match strategies. You can go back to relaxed hair if you feel that its right for you. I would say give being natural a little bit longer. When I was transitioning, I wanted to go back to relaxers quite a few times.
Lots of Luck, Love, ... And Curls!!!
