This is all part of the journey of life. There will be mountains and valleys...highs and lows.
Just know that nothing lasts forever and don't ever quit, for the end may be closer than you think.
When life hands you a lemon, make lemon juice out of it.
Stay positive....always see the glass as half full rather than half empty.
Pray, reflect, and meditate. We all need quiet time so we can see the big picture of life in its fullness.
Be grateful for what you have...count your blessings. If you list all you have to be grateful for on a sheet of paper, you will realize that things are not as bad as they seem.
Don't sweat the small stuff.
Last but not least: seek help if you need it. You may need counselling or a Life Coach or just a friend who will listen only.
Don't try to do it on your own.
