Help me have a good trip?

Alright, here's the scoop: I was relatively inexperienced at tripping (half-eights of shrooms a few times, once lemon tekked, 12mg 2ce swallowed twice) and thought I was ready for my big boy trip. The last time we had tekked it hadn't given a noticeable difference, so I went ahead and lemon tekked an eighth of shrooms.

Long story short, I thought I was ready and wasn't. I'd done lots of stuff on smaller doses so I thought I'd be good to get something to eat (got really hungry) with my sitter and two friends (who had done less). Things went sour as I peaked alone in a foreign place with a huge number of people around me. From everything that I've read (which is pretty extensive) it was a level 5 trip. Strong audio distortion and hallucination (voices on the radio talking to me, people on the other side of cell phones saying my thoughts, total loss of language comprehension), synesthesia, constant whole-field visual distortion and hallucination (everyone looking at me, visual loop in the car with a street sign), extreme body tripping, full on paranoia, schizophrenic delusions, literally just about every single 'bad trip' deal I've ever read about I had at some point. That's really not an exaggeration. The only thing I was spared from was ego death, and I believe that was only because I was so terrified and miserable that I didn't have time to think about anything at all except for primal emotions like fear of fire and 'friends good, yes.' and things like that. I came down a good, good bit and started doing better and had an alright hour and a half back to baseline.

I didn't want that trip to get the best of me. I educated myself, prepared and did everything I could to be ready. My girlfriend and I tripped together on a half-eighth of shrooms each a week later, not lemon-tekked. I was with friends in a familiar, secluded and comfortable environment and had the means to do most things that I would want to.

Within fifteen minutes we were both feeling it, which set me off guard. Literally the very first thing I felt was negative. Before I had any sensory effects I just immediately felt 'This is bad. The universe is bad again, just like last time.' Sound deadened, my body felt mild even outside, I felt paranoid and miserable again. My friend took my girlfriend and I to my place where I made a perfect environment. After half an hour to forty five minutes in the perfect possible environment I started to feel better, but I really don't know if it was because of where I was or if it was because I didn't have any visuals anymore. The part during that trip that sucked especially bad was that I had very strong body tripping - I had to pee, then didn't, was hot and cold at the same time, constricted and not, my feet weren't comfortable anywhere, etc. etc. After my visuals faded we played it safe awhile and then went on a walk and had an AMAZING time.

Okay, one final thing: I'm extremely emotionally stable. I'm not trying to be arrogant or anything, but I'm just never stressed, never anxious (I almost had no idea what anxiety was like before my bad trip), have no mood swings or any mental illness. I'm happy 95% of every day, have a great, comfortable life and just have the perfect mental setup.

With my first trip I was extremely dumb and messed up my setting and dosage; my second trip had great set and setting with a familiar dosage (although it was much stronger than previous half-eighths) and I still freaked out! I don't understand! I took a gram recently (3 months later) to work my way back in and didn't feel anything really. But I really want to have that enlightenment experience and I want to think as clearly as I do when I'm on mushrooms, but I don't understand why I trip bad! I don't know if I don't like tripping, or if I have some underlying illness, or what, but it really bums me out because that 'enlightenment' phase on mushrooms is one of my favorite experiences.

Help?
