How to cope with a full on phobia?

I use to have something similar to this (obviously not to such an extent, I would just panic and cry) and I eventually got over it. I sat myself down and made a list of what I thought really worried me about going to the doctor (or school nurse, or clinic). I wasn't afraid of bad news, I was only slightly afraid of needles and other things. I finally realized that there was nothing about going there that scared me, it was just going there. So after mentally preparing myself (and scheduling, cancelling, scheduling, cancelling visits), I went to the doctor with my brother who did the 'tough love' thing. He said he wasn't letting me leave. It's still tough for me to go to the doctor, but over the years I think I have gotten better. What I have is commonly referred to as White casaco Syndrome. I don't think you will ever fully get over it (because hospitals suck), but you can eventually learn to deal with it if you try to rationalize what about it scares you. You can control yourself better than you think. (I talked myself out of being scared of spiders). And breathe, just remember to do that so you don't pass out :)
-Don't know if that will be useful but worth a try.

if u have a bff u can talk to them bout ur prob if not try parents or maybe just and audult u trust if u have a prob get it fixed be4 it gets worse

You can talk to a counselor or someone who specialises in phobias about this. Medical procedures are nothing to be afraid of, without them, many lives would be gone. Hope this helps. God Bless.

What you need I think is a practictioner of Nuro Linguistic Programming(NLP).it worked for my phobia of birds, Not enitirly but to a point I can deal with it.
