10mg amitriptyline, 26M

Hi people I just took my first dose of the medication I tried gabetin last year for 3 days and I lost my mind I was spinning and couldn’t move so I stopped , I’m now trying amitriptyline for multiple reasons but just to list a few I have chronic nerve pain in my head, belly, legs, private area all of which is suspected to be from a slipped disc in my lower back (L4-L5, S1), I’ve got migraines a lot and pain in my grown area potentially pudendal nerve pain

Any suggestions and please give me hope I’ve suffered enough
