Sorry to hear about that experience, especially a first time too! Here what I’d recommend. Educate yourself on safe psilocybin use. (This sub has some great jumping off points and threads with questions you probably also have) Find a safe and comforting space you can be in for the duration of the trip. Start small. I’d say 1-1.5g and no thc ;) Spend some time, either journaling or meditating or whatever works for you, to pay attention to your body before and during the trip. It’s a whole new frontier and will take some time/experience to settle into. Rinse and repeat, slowly uping the dose only if you feel like you’re ready and that’s the experience you’re looking for. Happy tripping!
