recent change in my attitude to my stutter

recent change in my attitude to my stutter my stutter has never really bothered me until recently. i first remember stuttering in middle school but i am fairly sure that is just when i noticed it and have been in fact doing it my whole life. im a fairly laid back guy and tend to take things as they are so i just looked at my stutter as one more part of who i am, i mean i would change it if i could just wave a magic wand but it i want it gone in the same way i want to lose 10 pounds: would be nice if it happens but no biggie if it doesnt. as of a few weeks ago its been bothering me more and more. i blame my change in attitude on the fact that i am actually looking for a Real Job (at 30 years old and with a BA hanging on the wall, i figured it was time to stop being a cook). im in a program right now to get certified in CISCO routers with a guaranteed job interview at the end (technically, im between 2 programs, just got my network+ certification a few days ago). i was thinking about this recently and the realization hit me that every job i have ever had i got as a result of someone recommending me to their boss and there was either no interview or it was just a formality, while every interview ive ever had ended up with me not getting the job. is this just me being paranoid? if not how common is it to not get hired because the interviewer doesnt want to hire a stutterer? and what steps can i take to mitigate this possibility? i know stuttering is covered under the ADA but i *really* dont want to pull that card. also, even if this is the case, i think im crazy to even worry about this right now because the dreaded interview isnt until feburary at the soonest, but its just been bugging the hell out me recently and i need to get this out somewhere
