Is starting football at 15 too late?

I’m currently 15 years old and recently decided to sign up to football (soccer) training after school. For about a year now I’ve been completely engrossed with watching the sport and enjoyed having conversations about games in the premier league and the UCL with my friends. All of my friends have been playing football for many years prior and many of them play for clubs outside of school. I have only been doing Judo as my main sport until now.

I’ve quickly learned how horrible I am since my first session. I only go once a week after school from 16:30 to 18:00 and everyone takes the piss out of me. I am a complete beginner, I have no skill whatsoever and any attempt I make to try and control the ball is embarrassing. When the coaches split us into two teams, the captains never pick me and they all get pissed off when I am assigned to their team. My friend has even taken me aside after training to tell me I should quit to save myself the embarrassment.

I’ve wanted to go to training since Year 8 and I have literally wanted nothing more than to become a good footballer. I never joined the football sessions beforehand as I was terrified of the mockery and the laughter. Eventually I decided I didn’t want to look back at my school years with regret and disappointment of the fact that I never went, so I decided to sign up.

Another part of this that’s been bothering me is my family. My dad is really into football, and pretty much everyone on his side is as well. We’re all West Ham United supporters and football is a big thing in our family. My cousin played seriously and my other cousin even made it into non-league club and now works as a scout for the academy of Liverpool FC.

I’ve currently gone to three sessions and I’m wondering if anyone with experience could advise me on how to improve and further my skill level. I am completely open to practicing everyday during summer holidays and I have a lot of free time on the weekends.

Thanks
