Positive experiences makes me invalidate my transness.

I started T in December and haven't had much noticeable change, which is okay, I don't really mind since i want to take it slow until i get to a point I'm happy with my appearance. I will still relatively pass as female to most people despite dressing very masc (I often wear all denim).

basically I spent an afternoon today just out doing stuff with my dad, who is unaware (potentially unsupportive, but proud i do traditionally masculine things we connect on such as Hunting/Fishing) I am undergoing this and planning to change my name later this year, which makes me feel kinda guilty.
But i've figured out whenever i have a positive moment it makes me forget about the woes of my trans experience. Like as it never happened and there's no possible way I'm trans! Sometimes I will forget about my perceived gender identity and it would be the least of my issues and this again will convince me I'm not trans.
Just wondering if anyone has similar experiences?
