If my therapist was annoyed to see me I would not stick around. I see mine 3x week and I've never gotten the impression that he was annoyed to see me so often. I fear that's the case, but there's no proof of it. On the contrary, I get the impression that he values the continuity and connection this kind of work brings about. Before we started 3x week, there were plenty of times I asked for an extra session and I never felt like I wasn't welcome if he had the availability. You deserve to have a therapist that doesn't make you feel unwelcome.
