Sorry is this is kinda confusing , I am new to this

So I am a very introverted person (m16) and I have started running everyday because I want to work on my health and fitness.

So I have been running for about 50  days and I am quite enjoying it but I made my Mum promise not to make it a big deal cause I don’t like attention and that kind of stuff. Another important part is that my brother also does running and he has been doing it for years and my parents are really proud of him and when he reaches major milestones like day 50 , 100 , 1000 etc but as I am a more introverted person I don’t really like it when they do the same,

So the main part
I have just reached 50 days and I found out my Mum had made. A Facebook group involving close family and friends about my running and it made me very uncomfortable, I had to talk to my mum about it 

So am I the asshole for not happy about it
