Hello!
No I don't know what you talk about and I don't think it is the tobacco that makes you feel fear.
Maybe you are in crisis mode or something, did something happen recently that makes you feel fear?
Did you try snus?
It is an alternative to smoking so with snus you can quit smoking tomorrow without a problem.
If you quit smoking without using an alternative nicotine product your condition may be worse because then you have to deal with both your condition of feeling fear, whatever that is, and your nicotine abstinence.
Take good care of yourself, please avoid stress.
