Look at this paragraph...what needs to be revised?

Finding the right doctor is always very difficult. I’ve often found myself in a small doctor’s office with an unfriendly receptionist, who disturbed by my intrusion, would grimace upon seeing me. And so with that welcoming face for a greeting, I would sit anxiously waiting to see the doctor while filling out paperwork that I might not fully understand, but of which clarification would require my asking the cheery person at the front desk. With such negative vibes filling my system and a glance about the sitting area producing a picture of a tiny room, overfilled with chairs and tired people, the expectation of having a good meeting with the doctor always seem to drop precipitously. It was a meeting doomed for failure.
