There is no place for negativity in your life, thoughts, or spirit. You have to willingly 'look on the bright side of everything'. You owe this much to yourself. Your well-being is important. I know we like to help others but we are in no shape to help others when we aren't whole. Positivity will get you through hard times. You know what? Don't even think (or if you can't help it, correct yourself) in negative terms. Instead of 'I hope my car doesn't break down today' you should say 'I appreciate the fact that I am able to do what I need to do everyday'. No worries, no problems. Our mindset is often our biggest obstacle. So why let something that you control be a detriment to you? You don't have to... just change it.
Praying and wishing to be delivered out of a difficult situation is getting us nowhere. You should instead be praying for the strength, wisdom, and courage to make it through that difficult situation. Most times the only way to get over something is to go through it and that's where a lesson should be learned. My mom used to always say the most important lessons are always the hardest to learn and often they culminate from the most difficult of situations. So face it, life is not easy for anyone nor was it meant to be.
As I said before it will be uncomfortable and hard but with enough practice it will become something that you do without even thinking about it. TRY IT! What do you have to lose except for stress/mess? Get it, got it, great.
Inhale positivity, exhale peace.
