I'm a creep

Ok this is my first time using this but I'm 13 and I get super obsessed with any crush to the point where it gets concerning and right now there's this guy I really like because he's really kind and he looks really good for his age cause he's way older than me (to make matters worse Ig) and he lives on my street so I purposely walk by just to see him outside and i give my best friend updates about him all the time and sometimes her and I sit on a sign near his house so I can watch him and she finally called me out on how creepy it is and now she told my mom and I've been thinking about it all night and I wanna cry but I know I'm in the wrong and I wanna reach out to someone and ask what should I do but I know Im a creepy stalker who's obsessed and I even make scenarios in my head about him and it just gets so bad I've only ever talked to him like once and that's all I just got so obsessed there's something wrong with me
