How do i repress my nerve pain (usually results from increased stress)?

you should set yourself up with a good psychiatrist and discuss this with them. This is almost certainly a mental issue and nothing physical. Sometimes even some simple relaxants such as xanax or ativan will be enough to calm your nerves and decrease the pain. However the doctor will most likely want to EVALUATE you further and put you on a regular course of medication, most likely a anti-depressant of some kind. I have had issues like this for many years and trust me, getting help is much better than waiting it out.
