It’s a cycle of just bad presentations and interviews

It’s a cycle of just bad presentations and interviews I am so exhausted of constant horrible interviews and presentations. No matter what I do I still get stuck, I still trip over my words so much. Even when I feel like I’m not anxious. I literally feel like a failure atp. Everyone is getting amazing jobs and going ahead in life whereas I am struggling to even pass an interview. To say a single word. To say a sentence. Just wanted to vent and this is the only place people have had similar experiences as me.
