I'm terrified about not getting accepted into the military
Why do you think you didn't get accepted?
I want to say that I would never ever get accepted since I'm very bad at interviews
I'm sorry you didn't get accepted into the military and it's understandable you're scared about your future. Keep working hard and exploring various options.
I tried to talk to them logically but it didn't work. They wouldn't accept me.
Sometimes it's not what you say. It could be a number of things like medical history or space. You shouldn't beat yourself up.
