What would make you happy op? Finding out your number 1 happiness factors will turn you into the happiest person alive 
I am extremely happy because I wake up and count my blessings. I have healthy DC, I have travelled and worked all over the world world, I have had amazing experiences. Do I have a pension? No. Savings no.
As soon as you put value on comparative materialism you are going to be doomed to despair.
It sounds as if you have put all your ££ into your home at the expense of your quality of life.
I recently volunteered at a charity where the manager ( same age, nearly 60) said she has 7 more years to go to retire and hadn't seen the world or travelled much and that was what she wanted to do more than anything but didn't feel she could.
What a trap she felt she was in! But actually any trap you feel is only a trap in your mind.
I now volunteer in a nursing home where people 55+ go to with dementia and other disabling conditions.
Alot of them never got the chance to retire into the sort of life they had saved up for all their lives.
In your later years you will need to find £1000 a week to fund your care if your health is very poor or you have no children to look after you.
Just look at the statistics for dementia if you want to face reality.
God help you if you are not actively treating your body and mind as a sacred temple now because of you do not look after yourself, keep your health and fitness in tip top condition you could be storing misery for yourself further down the line.
Live life as if it's your last life! Sounds glib but honestly, as soon as you are focusing on others and not on yourself you are going to be divorced from finding happiness from within.
I make an active choice not to take anything for granted in life to enjoy every single day. Every single choice I make, from the bread I bake to the realisation that I enjoy giving and helping and being kind, which is why I stopped a former more lucrative career to start one which is more rewarding as I now have time to volunteer.
Having a big fat pension and retirement nest egg is for people who missed out on their best years of their life for travelling and living life to the full as far as I am concerned.
I am doing things now I won't ever want to retire from as I love it so much.
People talk about retirement as if it's the best thing ever. Yet why wait? It's important to do what is important for you now while you have the health and fitness as who knows what is round the corner?
So many people trapped in their homes looking after their partner whose health has failed before theirs and their hope for a wonderful retirement has gone out of the window.
Aim to make every day the best it could possibly be and take ownership of your own past, present and future and once you can see you are the captain of your own ship you can take the helm and steer it.
If you won't no one else will.
