it's just one of those days, I feel like giving up.

it's just one of those days, I feel like giving up. It's just a bad day that's been on and off for the past 2 months. My stutter keeps flaring up, this is the second night I haven't had any sleep and it makes it worse when tired. I've got 6h 45mins of my shift left and I'm hating it already. Days like this I just want to quit and find something else. I'm earning just over minimum wage so it wouldn't be too bad but I'm in a call centre and apart from the stress of stuttering, it's a great job. Days like these I just don't know if it's worth it. Its unprofessional, embarrassing and causes a delay in my calls at the customer expense and worsens my call handling stats too. While I do only stutter for a few seconds at most, it's every other word and some words I can't say and just say "uh uhm uhmmm mmmhh" and then finally splurt the word out.
