1) Okay, let's say you've been hypnotized. Fine, then accept this and move: accept that now, YOU are the one in control. Don't blame the hypnotherapist from this point forward. If you find yourself defensively wanting to rationalize against my point here, that you, yet again, consciously or unconsciously willingly giving up responsibility for yourself. That doesn't make you a good or bad person, it's just important to see that happening.
You want to live your life 'like a normal person' presumably a good, positive life. However, even most normal people will be negatively affected by other people. Learning to deal with these negatives is common to EVERYBODY. So, in that way you are very much like others. The details of your story are different, but your issue and your feelings are relocatable and can be understood by others. It's a valid feeling.
You're right. If someone doesn't follow a code of ethics, then it's meaningless to them. But for everyone one person that did you wrong, there are probably hundreds more that want to help. Don't judge ALL people as untrustworthy, because doing so will certainly set yourself, or others, up for failure again if you're unwilling to trust they can help. Trust is difficult, but we can develop trust if we are safe, smart, careful, and willing to have faith when the time comes to use it.
