DISCLAIMER: I am speaking my mind out. I appreciate any advices you all can give

I am not sure if it is my hormones playing games with me - However, I have an acquaintance that's also in the process of transitioning that seems like having a hell out of fun than me LOL now this is just based on the facebook pics that I am seeing. Hanging out with some cute guys and always seem to be on dates etch.
I feel like I am missing out LOL However, work has been toxic as it is and I have a second job that I love but it seems like work has been getting in the way of my enjoyment. However, I also acknowledge the fact that I have some resentment deep inside me - The feeling of I am better than this person. How come I am getting less than what she's getting. In the process, I am starting to hate men for liking women that are flirty and someone that sleeps around.
Am I jealous? Am I projecting my insecurities??
This is more of a rant and I just want to know if you sometimes feel this way LOL
