Keep you chin up buildingpaul! Something that helps me is this in it's most simple form (LIVE IN THE NOW) I mean it but the hardest thing is to remember to do it at this moment every time.
The PAST: fading memories, some good and some bad and some that just don't matter at all. PAST does not define you now, in the Present at this moment.
The FRTURE : Our dreams our ambitions , plans and goals (THE MAKE-BELIEVE WORLD) we create for ourselves is not living in the present ether. WE put so much weight on our make believe "ambitions..." that if it doesn't work out it ruins our day, life ect. STOP !!! and live in the now.
The NOW: is the present this very moment, this is LIFE itself and nothing more. The great memories you have from the past are those you were most emotionally attached to, the ones that are more vivid and sacred. When your with your daughter enjoy that moment and invest every fiber of who you are and the memories are made because you are now in the present living LIFE! Do this with everything, pour your soul out into the present/now and you will find life begins to change, because you start each day as if you meant to do it on purpose. Take control of what you can and instead of reacting to it. Many blessings my brother, get stronger
