As an instructor myself, it's always a worry that student pilots become disillusioned or anxious about their performance, when actually they are handling things as well as would be expected (or even better than would be expected!). To be fair, how would a student know what 'normal' is? It's such an alien environment, and there seems to be so much new stuff to be absorbed on every flight! I remember my first hours in the air and thinking exactly the same thing.....
If you've asked your instructor "how am I doing" and he/she has said "OK", then you're doing "OK"
If you haven't asked, don't be shy, just ask the question - they'll only be too pleased to give you the feedback. To be fair, with 7 hours on the clock you seem to be doing well to have covered as much of the syllabus as you have. But don't feel shy about asking for some feedback.
