I am 2 years post separation. For me, it was almost easy at the beginning because I was pumped with adrenaline, but after a while (probably about 6 months) all that adrenaline runs out and you are just left in a collapsed heap.
I am so much better these days, I have done life coaching and also counselling which have really helped. Also done the self help book thing, I can recommend 'You can heal your life', by Louise Hay (Hey?).
It really does get easier with time, but it is a long process, and this grief is totally normal.
You are only 53, your life can be full of adventure for many years.
I am genuinely happy being single at the moment, I get lots of affection from my cat! I have some great friendships, and I am full of hope for the future. Your life can be this way too I promise, you just need help with detaching properly from your ex. Counselling really can help with this, try and be open minded about it. Plus you will get on with some counsellers better than others, so don't worry about asking for a change if one doesn't suit you.
I see my 20 year relationship very clearly now, and while that's not necessarily an easy thing, it's much easier to see things objectively rather than with rose tinted glasses. When you've been in one relationship for a very long time, it is difficult to see it properly.
Good luck, you CAN build a great life for yourself you know
