I'm really sorry for you. I know how the feeling is when someone rejected us in every thing just because we're stammer. First, you need to talk with someone who understand you; may be your best friend, or someone from your city stammerer group or any person who could​ motivate you. You need to accept the stammering as it's, you can't completely cure it, but with regular practice (this is what I'm doing) you can control to some extent. Regarding the job-- just Kept searching until you get it, yeah, it'll take some time though. Search for such type of job that doesn't require much taking with the people. If anyone time you need help just ping me.
