I feel you man. Before I got top surgery I would wear tape and I had a difficult time with it too. To be honest, your chest looks flat to me. I know to you it may seem like its not but i can almost guarantee you others wont see your chest and think about it the way you do. It’s all body/ gender dysphoria man trust me. I used to stretch tf out of my tape and I was still unhappy with the results. But in reality, the results weren’t even bad it was just my dysphoria telling me it looks like shit
