Need Help

hi,

For majority of my life I have lived thinking I was better or above what I actually was. Whether that was soccer, school, looks or anything else I constantly overvalued myself. Recently I acknowledged that I was being cocky and arrogant, I realized that everything I was doing in life was being deluded by my mindset. This led to me developing this bad habit of being insecure and timorous. I live life putting myself under others, worried that I'm going to resort back to my old habits.

I'm stuck contradicting myself. I don't know how to be "normally confident" but I also don't want to come across as sheepish.

Given that, I need help. I don't know where to start or what to do to try and fix this mindset so I'm turning to the internet. If anyone has any tips or strategies, I would appreciate it.

thanks.
