Felipe,
You are freaking out!
Ya gotta 'chill ', man.
You are experiencing a series of unrelated circumstances
that are happenstance/coincidental.

Stress makes things worse..... with PN.

You are not doing yourself any good by flying off the handle like you are- in your myriad of posts, lately.
You are all over these boards (8 new threads in just 2-3 days) with questions that have been previously answered, but you ignore them.

We'd love to help, but the first thing you have to do - is calm down and think ! You have to treat your symptoms, feel better..... first, then you can delve into the mystery of the causes.

You may never find the answers.
Many of us don't.
But we feel better by making sure that our symptoms are being treated properly. This can take time for the meds to adjust, and for us to adjust to the meds.
That is your first priority.
