You could try therapy again maybe? Its not always easy to find the right therapist especially if you have a difficult to diagnose condition. Depending where you live the health system may be geared too heavily to over medicating people such as yourself and if this isn't what you want seek out someone who is willing to help you as a person without substances. I'd recommend this before delving deep into psychedelics. If you decide to do psychedelics please do so with a trusted friend / guide who can help you through the experience.
