How to have fun

Samantha • I am me.
So I am a young mom, I'm 21. I never went out for my birthday when I turned 21 cause I was pregnant but now I have my son and he makes me feel old!!! So I was wondering how other young moms still have fun and still feel young? I used to go hunting and camping and just had fun on the weekends but now I feel like I'm not allowed to go have any fun cause I'm supposed to be home raising my son any advice? Anyone else kind of feel this way?
