Forget this shit , every people is suffering disease one way or other , not telling us. Stuttering is our disease that's all. Lot of people will understand this speech impediment and it won't affect your skill in doing your job correctly. Fuck off the bad days and keep moving. Life is mixture of bad and good days for everyone. Smile dude , you are one of the heroes created by God. This disability is given by God only to those who handle it well and succeed. Talk happily to your family members and close friends every now and then and laugh and forget the sufferings. Lot of stutterers including myself undergone what you had today in your life. Years passby ,level of maturity and stubborness will allow you to talk about better and make you a complete person. Chill up!!
