It destroyed my confidence, but I started to realise that working on myself and the way I perceive myself helps much more than anything other can do.
When you listen to others is to share joy, not to be let down, criticism is important and we need to understand it, but there is a line.
Never feel ashamed of who you are, and if there is something you want to change because YOU find it important, you can work on it, there are no dead lines nor is there any hurry.
And listen, just from your question and the way you say it, you sound like a nice person so don’t let anyone bring you down.
