Im antisocial with band group

I need to share and work with others talents in band group. I’ve only gone maybe 3 times but the mh center and others say we should work on my originals for pride fair in august… I am not an aggressive go getter tho. And i have never been in a full band setting more than 10 times in my life… Im aching in my head and chest because I’ve neglected this band for months

I played solo at the mental health fair behind the center last month but the band will take more practice and the pride fair is at the downtown park plaza i think
