Originally Answered: Why I'm I always being too sensitive?
Maybe you were sensitive from birth. Your parents didn't help. But maybe, things were tough for them. Maybe they did the best they could and really do love you. It isn't easy to go through life with thin skin. The real world outside of the family culture is even harder. At some point, the responsibility is not that of your parents and their faults in your upbringing but your own. That means as an adult, regardless of childhood events which are seen in memory, get out and live. Learn it is not all that easy. Running to others and complaining is not a way to win friends and influence people. Make it happen for yourself. Leave the past behind, and be a grown up. Get your own flat, pay your bills, and forget those people who are genetically within you. You can even move away.
On the other hand, someone changed your diapers, fed you from a bottle or breast, tucked you in at night, sent you to school dressed properly, took you to the doctors. There is no law that says one has to be happy. Live life, and if you think they were bad parents, get married, and do a better job. Get away from drama. Play good music at home (your home), light candles, have essences to impart pleasant aromas, practice yoga, and change your lifestyle. Say, "No" to drama in your life. Make it simple. Be an easy person for a mate. Aggreable and supportive.
Unfortunately, life has its ups and downs. That goes for everyone, and we are not all treated as we wish at every moment by every person. We have to take our lumps as best we can, and move forward, not backward. As you wrote a lot, I can't respond to every statement. If you want to go the therapy route, it won't help teach you how to tell these people to back off and grow up. Also, playing sensitive me, is a sure route to victim me. How about strong me, and shut up you guys me, and are you looking at me? Say it, don't think it.
