Okay so my biological father wasn’t really in my early life a lot (I’m 17 now) like when I was young he use to promise to pick me up and never showed up sometimes I would be waiting outside and he never came :/ the only person to cheer me up was my step dad who is no longer with my mother. But now since I’ve been visiting my hometown with my mom I got to see him twice and he feels like a stranger to me   just a man who provided me life so my mom could give birth but while I was there I at least I got to bond with my aunt and cousins because I barely get to see them too. what’s upsetting because  during those years of my biological father not being there I had my step-father who took care of me like I was his own he was there since I was like a toddler and then he and my mom got married and had 3 more kids but at the age of 9/10 they  divorced and he left but he still tried his very best to spend time with us and all that started to change a lot more now because he’s married to a new woman and he doesn’t really claim me anymore like that...he went from calling me his own daughter to saying “Just a child I took in”I guess he can do that now since they’re divorce but it still hurts to not really be claimed like that maybe I’m just overthinking it but the main reason I’m starting to panic is because my biological father is starting to have a lot of health issues involving his heart  and what if he (I hope not) passes away and then I’ll just be left again? I just have so much high anxiety thinking about that.
