it didn't feel right

staring at the English Textbook year 5 thinking how am I going to survive for another 5 weeks. seriously all those comments from supervisor really dropping my soul and demotivated me to carry on. I know I shouldn't let her feeling like I'm not good enough. that's cruel. but that's how I feel right now. she makes me rethink back how did I end up here in this campus, learning how to be a teacher. so, that's how I get confused. it's wrong for me to have this second thought and a tiny regret of what I did. however, I made a promised to myself to not looking my past with regrets.  because at the end of the day, I want to say to myself that I make a right decision. but I just don't see it how those comments are building myself up. it does affect how I teach and plan a lesson. and why do I have this second thought again..
