Do you know that I keep all the intensity of my pain to myself since other people in my life don't know how to respond?
Are you serious because why would you keeping the intensity of your pain all to yourself?
Because it's my pain, isn't it?
I understand it can be frustrating when people can't understand our pain but it's also bad to keep all that pain bottled up. You should speak to a therapist. A therapist can help you better communicate that pain to others.
Psychologists don't know anything about pain. They are useless.
You might be underestimating them because they really do know how to deal with this kind of stuff. Rather than jumping to conclusions about them, you should at least give them a try first. You might be surprised at the outcome.
