Yea, in simple terms it has a multiplier effect on everything you experience. If feelings go bad, they can go really bad and remain that way afterwards.

But you commented on suicide. I also have a friend who unfortunately passed this way. Do you have any data on this? From what I have seen, studies have been limited.

I had read somewhere on erowid years ago a study where an increase in mental illness and suicide after psychadelic use was positive but less than an increase seen in another study of people who had completed religious quests.
