I understand you bro the emotions you are going through, i have also been through this. The interviews, the shame and the depression. But never give up hope. I also have a mild stutter, mainly plosives (P, K, B, G, and T), which cause blockages in my speech. I've observed that my stuttering is more of a "anxiety inducing". I stutter little to none when I speak in Hindi or English to my friends, family, or even on phone calls. But whenever I have to introduce myself to a group of strangers or in a meeting, my anxiety shoots up, and I get completely stuck not even a single word comes out even it is easy to say without making prolonged periods of weird faces. It's so exhausting and stressful. Every day I wake up and think today might be the day when I will speak fluently. I've started asking random directions to complete strangers whenever I go outside, trying to desensitize myself from anxiety of bieng judged.
