I really just need to vent

[AgentK]

My sister is pregnant the baby comes this month , don't get me wrong I'm super happy for her . But it seems nobody cares about me anymore my dad is with her and my mom leaves for work every morning so I'm alone and I had to go to get on the bus the very first day of 10th grade it's just really eating me up inside . My mom says I get to go to school by myself because I'm more mature than she was and more independent but idc how mature I am sometimes I don't want to be alone in the morning it's hurtful like idk how to explain it . She's snuck off to be with a boy before and got caught few weeks after that she was back hanging out with her friends now few years later she's pregnant and everyone's happy . I have good grades don't have male friends except ONE and I can't go out with him or do anything even though they've known him for 15 years . It's ridiculous 🤦🏾‍♀️🤦🏾‍♀️ I promise I'm not gonna be stupid like her and make bad decisions but they don't trust me I'm not even aloud to date . I'm 15 turning 16 in October. Never gave them any reason to be like this to me I just dk anymore . HELP
