Is it normal to have such powerful mental blocks?
Every time I want to change, or do something altering to my life that involves my mindset or personality, I slam against these huge mental blocks. They're immense and invisible, and ultimately physically numbing. I can barely get past them. Some mental blocks I have are being more optimistic, trying harder to be more open and make friends, not care what people think. I think in my head, "I want to talk to this person," and then my mind just shuts down and I can't do anything. When I think about being a more optimistic and open person, I feel myself become dead-weight.
Is it normal?
