These journeys are purificatory. When in a good environment, ones diseases and ignorance become starkly apparent. This is scary. I better do something. Also, shaytan works extra to distract you with was-wasa and what not.
Most newcomers get a little sick.
I personally got very ill in the last week and actually thought I was going to die. Insha Allah the illness is purification and not punishment. One of the good things about getting sick is that all the shuyukh come visit you, especially if you re a visitor from a far away place. Not rude audacity, but just don t be shy. I just went to their houses.
