It's likely you learned a lot about what not to do. Good leaders will find it attractive that you have experience with mistakes and failure, both your own and others', just like they'll put cushions under their employees when they mess up because they've just payed for them being likely to not do the same mistake again.

Might take a while to end up talking to one but they're out there. Confidence and motivation are likely the bigger problems but it's highly dependent on where you live and how what would be the appropriate way forward in those areas.
