Don't be afraid to question the Bible; how else will you learn? Don't believe something you hear on blind faith, either - a general rule is that unless someone provides some Scriptures, don't believe it (or look further into it).
There is a lot you can do to 'cope' with the troubles of the day.
Something for you:
Jesus provided the means for us to live happily in this life. Jesus IS that means. Jesus IS that good you're looking for. There's too much for me to go into detail; just focus on God's love for you, read the Bible, and meditate on it day and night. Not easy, but totally worth doing.
As a personal testimony, I don't watch the news, or much television. I don't read the newspaper, or go to movies and listen secular music. As a result, I don't think about a lot of the crap that's in the world today. That's not to say I'm not aware of it, but I don't think of it as often, and when I do, I thank the Lord that He's taken care of everything for us by His grace.
I'm sorry that the love of your life left you, I... That hits home a bit, I'll be honest.
As I asked God, 'How could someone cope with that?' He answered...
'Focus on Me.' It may not be easy, but it works. Just look up. He's there, holding out His hand, ready to pick you up when you've fallen down.
Remember - in the walk of life, if there's only one set of footprints in the sand, that means He's carrying you
. Remember also that, if you're looking for good, read the Bible - there's so much good in there it might overflow off of the pages and into your life
You are in my prayers.
