Nothing wrong with having a fear of being betrayed by a close freind, i have more than once, and ended up being accused of doing something i never did, and its stuck with me for over 20 years, and its not paranoia.
Bee's i dont blame you first time i got stung it hurt a hell of a lot more than i thought and, ive been through real pain more than once, woman i worked with used to be a nurse thought i was having a heart attack because i got stung on the chest, also a good freind of mine at school got stung the first time and that was the way he found out he was allergic to bee stings got stung in the throat, within a minute he's throat and face had blown up like a balloon, he couldnt breath, we were giving him mouth to mouth to get air into his lungs, if the ambulance hadnt show up when it did he was dead, lucky the ambulance station was across the road from our school.
I hate spiders i live with cans of pesticide near me, i usually have 5 cans in my work room and 2 in my bedroom, i had a spider the size of my hand on my wall, i got a slingshot put a paintball in it, never found any remains ever.
Also have a fear of needle, syringes, basically i have to take alot of medication anytime i have to have any procedure or blood test, i give the person a warning, because i have really a bad reaction not necessarily for me but for them, last time i went into hospital they kept me waiting for so long my medication ran out it took 9 people to hold me down.
Dentists, but a good reason, one dentist put a needle in my gums to numb them to remove some teeth, usually, unlike now they had to wait about 5 minutes for it to work, instead he just pulled my teeth and my gums werent numb, my gums went numb after i left, i screamed alot and he abused me constantly for screaming and thrashing about .
