I would like to emphasise what
@dumpsterDiver said about your actions during the events that caused the abort.
If you have any "crisis", your actions should be
1) Stop. Stop your activity to allow you to address the situation
2) Breathe - nice slow relaxed breaths to help you stay calm
3) Think - give yourself a few seconds to think through what is happening and how you can address it. Virtually all issues can be worked out given calm thought.
4) Act - only after the above do you take any action. You should be relatively calm and methodical in your action because you aren't stressed.
The only "urgent" issue (apart from medical problems) is lack of gas - in that case your plan is exit the water as soon as possible (and safe to do so), air sharing with your buddy if possible.
I do suspect you have "gone in rather deep" with your choice of early dives. My early dives were nice and relaxing shore dives which gave me a chance to get used to being a diver and a buddy as opposed to diving on a course with an instructor.
I have aborted a dive (think it was about number 10) due to poor vis (lost my buddy after dropping 3 m - couldn't see his fins despite being about 18 inches below them).
Looking at your reasons, I would say that:
Dive 1 - practise mask clearing so it becomes second nature. A relatively simple lift the edge to partially flood, flush the water round and then clear would have been the best course.
Dive 2 - you should have waited longer before diving after all your hassles getting your gear sorted. A 5 minute rest might have made a big difference.
Dive 3 - you were sick so no issues calling the dive (note that you can blow chunks through a regulator if need be - I might suggest a very good rinse afterwards though).
