Making me nervous !

My new manager is a guy 20 years older than me. I’m 24, I’m new to this job field and I just feel terrible all together. I’m in the training stage and he tells me by his actions that I’m doing a terrible job. He snatches things from me, ignores me when I asks questions. Also when I ask him to show me something he beats around the bush. There is also one other female that works with us, she’s my same exact age. They get alone fine. They talk and smile at each other he even bought her lunch once. It’s like they both feel they same way about me like they are a team.
