I break down mentally and feel horrible because of how sensitive I am and how emotional I get. I have every single sign of someone who is mentally weak. I easily get emotional by anything that's even critical and seems disrespectful to my self-worth as a person. I can't do anything correctly and fail at the most basic tasks ever. I keep fucking up a lot in my life. Being stupid and worthless is just the whole summary of my life, nothing else. This has killed my self-esteem a lot over the years. I have thought a lot about why I even exist to endure such suffering. I am getting tired of this and I want a complete change. I was constantly told that I was worthless all my life and that belief is stuck and hard to remove. My family, peers, and friends have been calling me worthless and I am just a broken, useless human being. I want to change and grow thicker skin. Many people tell me to stop caring what others say but that's not easy. I don't know what exactly to do and to not be sensitive anymore. Can someone please give some advice on how to stop being such a baby?
