I just read what you wrote above Ozzy, that really is terrible, it truly is...37 is no age at all, when you describe your feelings, it could almost be me, as it was April my wife passed away too.
The impact on our future life if indeed we can call it a future when the other half is no longer with us is indescribable, people who have not gone through it themselves really don't understand, because you can't unless it's happened to you. I still wake up some days thinking it was all a nightmare, and then reality hits home and you realise you have to face another empty day on your own without them being part of it.
It's over 5mths and occasionally I still struggle accepting what's happened, as though it's not fully sunk in yet that I'll never ever see her again....and I'm sure you know that feeling as many here do also.
You are right though, that the way forwards is to find something to occupy our minds a bit more, something I've not done myself yet, but it is something we need to do, being retired and fortunate to be able to have plenty of holidays away, in recent years my wife and I have been having 8 or 9 breaks throughout the year, ticking off things we had on our bucket list, many we succeeded in doing, like touring Italy, Austria,Switzerland for over 3 weeks last year plus a few other countries but sadly there were still a few places we never got to see. I've been away 3 times for 1 week breaks since my wife died, as I sort of feel I need to get away, and I go to Scotland again shortly for 9 nights away, but the truth is it doesn't really help, knowing she will never again occupy that passenger seat, and I also miss the conversations we all have during our travels, it's just not the same, it's the loneliness I'm finding hard to get used to. I never thought in my wildest dreams how you can miss someone so much until it happens to you, I can think of nothing worse, but somehow we have to continue and pick up the fragments of what is left.
I agree with Emz2014 comments, as I also found myself just lately getting the odd really bad day, people say that happens often a few months down the road. It's good Ozzy that you have friends, because I'm sure that must help, and cycling and fund raising events are good too, it means you are getting out meeting people, it's something I need to do, maybe not the cycling though...lol
Try and be strong my friend, and less of those dark thoughts, I know all about those, try and push those out of your mind. BTW never apologise for a long post, mine are always long...lol I sincerely hope things improve for you, as it sounds like you've had a horrendous time Ozzy with everything happening at the same time.
You take care.
