I can understand the anger, the anxiety of the outcome.
Unfortunately, stress is a part of day to day life, because of how the anxiety will have your brain telling you to second guess yourself and the decisions you make. Being rueful is again part of anxiety, and I know you can't help wether you are right or not!
One thing that I have learned from being so close to sport, is you can look back, but that's history and you can't change it! What you do is look forward and get it right or change your choices then! Thinking about the past will interfere with your present options, so you decide on the present circumstances.
If you're not aware, brexit will not be over for years yet!
The brexit deadline day, (now in January) is just the start!
There are so many things to be sorted afterwards, some political analysts believe it will still be another ten years at least until we have a full 'brexit'!
The decision to leave, should have been decisive, the trigger for article fifty, could have been decided not long after the vote itself!
The dawdling May government was caught up trying to please both remainers and hard right brexiteers!
Before the election in 2017, we should have been well out!
It was a democratic vote!
But now, because of parliament failing everyone and the really bad deal from May and Johnson, we are stuck in limbo, I don't believe that the forthcoming election will help in any way, we will have a hung parliament, no overall majority, and a minority government, which won't get anywhere!
The country has all major parties arguing between themselves about brexit, and the division in parliamentary seats between the yes and no will let other parties such as lib dems or the brexit parties pick up seats.
So as with the way we decide elections, first past the post, that will cause a hung parliament. That system only works with two parties fighting.
The northern Irish parties will be crucial in supporting the minority government, as will independent, plaid cymru, Scottish nationals.
It will be very interesting.
