So me and my friend got offered trials for a club that took place today and as I we were in the line waiting to register I told my friend I'll just watch him that I couldn't do it the pressure was to much I was getting really nervous and couldn't handle it then i was like shaking and sweating and my face was going red so I waited in the stands , while I was watching the trials I calmed down and instantly regretted not doing them but it was to late does anyone have any advice on how to help for next time I get trials or how to build my confidence ? I'm really disappointed in myself
