I had therapy last year for a phobia. The phobia will never go away of course, but I learned ways of dealing with it. I haven't seen the therapist in over a year now, but prior to those sessions, I had not had blood drawn in over 5 years, had not had a tetenus shot in over 20 and refused any type of needles unless they were life threatening...not even a finger prick. I also poured tears with every dental procedure requiring novacain.
Since the therapy, I've had blood drawn several times, I purposely scheduled a blood test and donated blood at the Red Cross to boot, I also purposely scheduled a tetenus shot and had a skin tag removed, requiring a numbing shot, that I'd been wanting gone for years but wouldn't dare do it. I've also been able to go through novacain several times now on getting my new bridge and never shed a tear.
I've learn to cope with it and find ways to ease my anxiety before the procedure, to breathe and not tense up so that it's over and done and I don't need a hygeniest to blot my eyes instead of my mouth.
