I am wondering, why do you take psychedelics if they make you suffer? I mean, having 3-4-5 difficult experiences is ok, when you are curious and inexperienced, but why did you continue tripping after that? You had at least 16 trips, and IMO, it is not a small number.
Also, when did you have your first trip(2 years ago, 1 year ago, 6 months ago)?
Psychedelics are certainly not for everyone, but if you managed to have 16 trips and if you ask such questions here then psychedelics probably are for you.
Do you have an idea why you have negative reaction for psychedelics? Maybe we could help you.
As for general recommendations, I second emphatogens. If you don't have access to MDMA, try some Methylone, it is readily available. Have 2-3 experiences, and if they are good and positive, give psychedelics another try. EDIT: ok, forget about it, I checked your posts list and you seem to have some experience with this type of drugs.
I also second the idea of changing setting. Take your dose indoor, turn on the music you like relax and try to be positive about the trip. Personally, I couldn't see myself taking psychedelics outdoor until I had some amount of experience. Setting have great influence to the trip for me.
Also, make sure you don't take high dose! Take moderate amount!(it is 16-20 mg of 2C-I and 10-12 mg of 2C-E for me).
