Hi Prion and congratulations! Don't be too hard or judgmental on yourself. You have lived in a fog for however long and now you are slammed into reality!
The past is the past, you can't change it so don't try to. The future however is something you can and with knowledge from the past you can make yourself a great future!
You may find that you are more irritable, impatient etc. That is ok, but try to "count to 10" if you can. Although this is simple, it will allow you to take a couple seconds to look at a situation and attempt to make the best of it. This is still a huge problem for me, so I am not making it sound easy, but with time you will learn that in most cases it just not worth getting overly excited about some other persons faults/short comings etc.
With time, the irritability will fade away, your mind will become much clearer, things will make more sense. A good friend of mine told me this acronym:
S on
O f a
B itch
E verything is
R eal
Scarey at first, but totally true!
Be well and all the best!
