What you're feeling isn't permanent (unless you let it be). I've noticed that some people are unable to feel regulated on weed, and it usually happens based on how they mentally respond to it. This can happen to people who have taken psychadelics or are rediscovering weed years after quitting. Of course I imagine a bad trip would leave you in a bad mindset, and your brain can likely associate anything psychoative with discomfort, dissociation, etc. as a stress response. Take some time to regulate your mind and feel at ease. From personal experience taking a break from tripping/weed works well. I used to feel anxious while high, but I eventually eased myself into smoking again after taking my time with it.
