Could a bad weed experience have caused me trauma or even minor ptsd?

Im 15 and 3 months ago I tried thc and took way too much and had a massive panic attack and had the worst day of my life and since my life has been constant dpdr and existential obsessions and horrible anxiety and health obsessions. When I think back to this experience (the weed itself experience) I get even more dissociated and scared of weed. Has this experience caused me trauma.
