problem is with you... I do not mean to discourage you but the fact is you went to the job stating you have several years of experience. Obviously, the team would expect you to show that experience in term of work so when they do not find that, that resulted in your situation.
Now, the best way is, you handle it the way it comes. Be nice, do not show attitudes, be polite and do not ask simple questions.
Like somebody above said, get a support outside of your work. You might need to pay for that.
If all does not work, just quit and find another position.
