How can I hide my weaknesses from those around me?

Maybe you need to ask yourself why you need to hide that weakness in the first place. It can really help to open up someone you trust.

You can't, eventually they'll see them anyway. And that's fine. You should show them - it's a part of who you are. And the best thing is, everyone has them so no one cares about yours. Your friends will help you with it and there's nothing better than that. So don't hide them.

I believe we can only hide things for so long. Eventually the truth has a way of revealing itself. Overall though our weaknesses aren't something we need to be scared of, if we work on them then we can get stronger in those areas thus we are no longer weak.

I don't think hiding is the right way to go about it, everyone is weak in one way or another. I think instead of focusing on hiding it, you need to focus on what you can do to become stronger, to overcome your fears. It is not shameful to be weak, but if you want to become stronger you have to work on it. Its very similar to wanting to become physically stronger, you have to work out, and its not easy, it takes a lot of work but in the end you'll have a lot more confidence and won't feel the need to hide.
