Sounds like you learned from your past experience and are integrating it well..i think you'll be fine. I've had horrifically harsh lessons from both lsd and mushrooms one week.. and then humbling angelic experiences the next week-as long as i strived to learn from those rough experiences and do what needed to be done in this reality before going back in. The bad trips were, more often than not, the ones where i learned a great deal about myself and the world..With these things i feel that you don't get what you want, you get what you need. I totally understand how daunting it can be to trip again after a tough experience, but in the end it is usually very rewarding to be welcomed back with loving arms. To me there is a big difference between facing harsh realities about yourself and learning from it, and dealing with delusions and looping unproductive thoughts
The delusions that can creep up are myriad and hard to decipher if you spend too much time thinking about them..you can't be afraid to just laugh at yourself once in a while.. no reason to blow it out of proportion..worrying about it will only make it worse IMO. A good technique to avoid drifting into the negative thought patterns from previous trips is to ponder all of that just before dosing, or on the come up. I go through all the bad things about the world and myself that might creep in and drive or darken the experience in an unproductive sense. That way, by the time the trip starts you will probably be really bored with it, and can then get on with the experience without being pinned down by them. McKenna suggested this and I've found it to be very helpful
