Welcome to Nexus Mark,
You've probably made a good decision to hold off on any more entheogen use until you can get your life on firmer ground. it's certainly not something that you have to rush into. It's great that you had such a positive experience with spice and got a lesson on what is possible (yes, love is the key to everything!), especially coming from such a dark place. Still, I think you will be able to get more out of your journeys if you first can learn more about yourself in a straight mindset and establish some core beliefs to live by. Don't worry, you can (and will) always go back and make modifications to your belief system, but it will give yourself a baseline or "launching pad" so to speak, to explore from.
I have no idea what your health issues are, but you really should find a health professional to help figure out what's going on. You need a healthy body and mind for the difficult work of self examination, but it's the noblest path one can take. Best of luck on your journey.
Peace
One more thing. Yeah, tripping balls in P.E. class is probably not the best of settings.
