On the surface I'd say it isn't out of the norm for someone your age to not know what they want to do. Look around, explore, try not to add undue stress, try new things. You have time. Many successful people have found it later in life, you can always change "what you do". As for the stutter, I'll focus on the opening. For me, it was accepting my stutter. I'm not a stutterer, I'm a person who stutters. It does not define, dictate, determine who I am, or anything of the sort. They're are purple that will put roadblocks up in front of you for myriad reasons, one of which might be because you stutter. While I couldn't prove it in court, I believe it has happened to me. Don't join them. Don't put roadblocks up for yourself. For me, acceptance and ownership has helped. It hasn't eliminated my speech impediment, it hasn't gotten rid of the assholes in the world. But it has helped me focus on Me, and get myself to a place where I'm happy.
