Has anyone had hypnotherapy?

I have a severe phobia of house centipedes and tonight there was a massive one in my room. I started screaming and crying and hyperventilating and I couldn’t calm down. Someone else came into my room and killed it but since then (2 hours ago) I have not been able to sleep and have just sat with all the lights on looking around in circles for more of these terrifying creatures in my room. I understand that my fear is completely irrational and yet even the picture of a centipede can cause me to cry and shake. I hate being scared because it affects my sleeping habits, and how I act. I have been considering hypnotherapy and was wondering if anyone has tried it for phobias? If so, do you think a phobia like mine could be treated with hypnotherapy?
