He said "you are hard to deal with" and I should leave him alone. I'm very anxious and I want to call him. What to do?

I sent him a text, he said he is busy... I sent another one and he got fed up. Said that I'm too much.

Later I visited him at work and he said I should leave him alone.

Now I'm very sad and depressed. I want to contact him. What to do?
