I think I can trust noone anymore after 6 years
What makes you feel that you can't trust someone anymore?
I don't know but nothing seems right anymore.
If you feel this way, then maybe you should talk to a professional. If there is no reason to trust nobody, you should not feel like that.
I don't want to lose.
There is nothing to lose about talking to a professional. You will learn more about yourself and can get back to trusting others.
