I need advice, I have a riding problem

Hello everyone, for a month now I have a problem every time I ride, I bought my motorcycle ( it's my first) a year ago ( Honda Africa twin 750 96') and together we ride at minimum 300 kilometers every week, but I feel like I have become a worse driver as I was a year ago, I can't swift gear properly anymore, almost in every corner I feel like I am going to fall, I can't trust my bike and I don't know why!Someone who had the same experience, how did you manage to overcome this situation? via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/bt7rsh/i_need_advice_i_have_a_riding_problem/?utm_source=ifttt
