Hi,
This is mainly a psychosomatic disorder type of presentation. You shall need to consult a Psychiatrist for help and will need certain medications as well for support. This problem can be overcome with treatment. Keep yourself relaxed and dont hesitate to take psychiatrist's help.

lol.. Don't take meds because of this problem. Just gotta man up and face your fear. I've never understood unnecessary phobias people have, there's no point in holding on to that fear - at any point you can let go and realize it's no threat to you and worrying about it will only make you less happy.
Maybe I have more control of my willpower than others, but for me I have eliminated many fears by simply reasoning them out of my head.
