Cognative Behavioural Therapy.
I had a great many sessions
it wasn't a short thing!
At first, it was talking about it, about me, about my feelings. Then some visualisation. Some work on what's the reality v my fear. Talking through what I think is going to happen. Breaking that down. Confronting it. When you actually sit down and talk about the reality of it - you see just how daft it is! Then one session she brought out a needle and put it on the table. I didn't have to look at it, touch it or anything. It just had to be there. That was a very difficult session!
I worked all the way up to holding it! over time. Then I worked up to having it taped to my hand, then taped to my hand for 24 hours.
It is a very slow thing and you are in control of the pace. They don't walk you into the room and throw the thing you're afraid of at you 
I had let the fear get out of control. Crying, fainting, putting myself at risk - because of a needle! How daft is that? I can't believe I ever let it have that power over me.
I won't lie to you, it's still not my favourite thing
I have to use what I learned in terms of breathing exercises, visualisation etc - but I can cope.
You can too.
