Not feeling confident at work?

So I’m brand new at this job in a veterinary clinic. this is the second week and I feel like I constantly have to get peoples approval. the first day I forgot paperwork, and a different day I forgot to give back the vet tech in charges key so she had to come out to my car and get it which I feel bad about. Then the next time I was there I almost forgot a water bottle and she was like look what you forgot. I feel like such a forgetful person. The veterinarian never talked to me or looks in my direction I didn’t even know it was the veterinarian and it’s a small clinic. All the of the female workers there gossip and talk bad about people when they aren’t around. I have to stay here and receive training to be a tech for a year and a half and I just am not good and holding things in when people are being jerks I can get an attitude easy. It’s really hard.
