The Degree of my Sensitiveness

Sometimes in my life I become like a fragile crystal. I can break even with a simple scornful look or remark. I get bothered of people trying to give me a message while they speak in jest. They may not even want to see me upset. They speak normally as they may speak to anyone else ,or they simply want to tease me; so, I cannot blame them!
The problem is with me and I know where the problem comes from. I usually don’t judge people by their appearance, the years of their study and the amount of money that they may have in the bank. I start to make friendship with anyone who is in front of me like a child. We become intimate friends in a fraction of second and in a few days he/she may tell me something I may not want to hear!
