new momma

I got a question for everyone out there...so I'm a teenager living at my parents house and like before I got pregnant I was the girl who was always out partying, hanging with friends or meeting up with new people all over my town. I was just wondering if anyone feels that way or am I just overthinking it? I lost all my friends....and I still have people hitting me up who think they are my friends but they like want to party and drink but I have a baby girl on the way who I want to know I didn't give up on her and throw her away once she was born. I want my baby to know I was always there taking care of her. I just need people's advice on it. I want to know why I feel this type of way not having friends or being able to catch a bite with my friends ya know?
