I can relate, I often used to have irrational anxiety...for such stupid reasons and it was embarassing to talk about - when I was young I was terrified one of my yo-yo's would break...then it was that I was going to die from a blood clot, and then that my brain would be starved of oxygen and I would die in my sleep because I slept in an awkward position. Intellectually and rationally I knew these notions where preposterous, but my underlying fear made me terrified, and I would take compulsive measures to combat them - checking my jugular vein, coughing after chewing making sure I didn't choke... It was terrifying, and I was in a prison of anxiety that I could never share. One day I had the worst panic attack, for no apparent reason, I woke up at about three in the morning (my time of worst fear, since it is dark and everybody is asleep and cannot help you), and I felt I couldn't breathe, my heart beat faster and faster, like nothing before, so fast that my whole body was vibrating and buzzing. I didn't know what was happening to me and I genuinely thought I was going to die, a REAL genuine fear - death was that close at only 17 years old, the day before I was going to meet the person I loved at the time. I rushed into my mum's bedroom for help and eventually I calmed down. When I talked about it, the turning point came - anxieties are only our own mental processes for self preservation - normally they are useful (I won't put my hand in fire again, since I'll be burned and feel pain) but they can be strongly associated with other matters, for no apparent reason (why should I have been so worried about yo-yos?). When you realise this from an external perspective and that you are fearing a genuinely unlikely event as a natural reaction, but it is not the true reality - you can gain this opinion by talking to others openly and gaining an outside view, ideally one that conflicts yours, and placing your anxiety in a real context. Of course, this doesn't totally eradicate you fear, it may occasionally resurface mildly, but you will be in a far stronger position to defeat it. If you have more severe anxiety, then a psychologist may help, but so are people experienced in life, which may be more helpful than you can imagine.
