You lost your confidence earlier this year, didn't you? You can say you didn't, deny it all you like, but you did. And who could blame you, given the circumstance? Hardly surprising.
But you're coming back. Slowly but surely. You're learning how to deal with that awful tight, fluttery feeling in your chest and the tightening of your throat. That deep breath that you're exhaling before you even realise you've inhaled. A few more measured breaths to relax you before the feeling passes.
Keep doing this. Keep breathing. Keep putting one foot in front of the other.
Don't shut yourself off. Don't build up those walls; they take ever so much time and energy to tear back down.
You know all this. Remember that thing you read: What people think of you is none of your business. You just do your own thing and you'll see.
You'll be alright.
