How do you deal with bad things that happen to you?

First, I know about the problem then resolve it.

"All paths are the same: they lead nowhere ... Does this path have a heart? If it does, the path is good; if it doesn't, it is of no use. Both paths lead nowhere; but one has a heart, the other doesn't. One makes for a joyful journey; as long as you follow it, you are one with it. The other will make you curse your life. One makes you strong; the other weakens you."
(Carlos Castaneda in 'The Teachings of Don Juan: A Yaqui Way of Knowledge')

Be patient and control your emotion. Don't be negative in condition or situation. Time will always fix your problem.

It depends on the situation and other thing

Thank you apsense. You guys have helped me with useful advice as well as relieve this bad mood

1. Release your frustrations.
2. Realize you are not alone.
3. Being frustrated isn’t going to solve anything.
4. Know you always have a choice.
5. Objectify it.
6. Focus on what you can do.
7. Ask for help if you need to.
8. See it as an obstacle to be overcome.
9. Identify the lesson learned.

Be patient think twice and then take action to resolve the matter.

There are no bad things. Everything is made to deal with and to have good things.

Be patience, don't take any decision in anger or sad, just calm down yourself first and think about the solution

Be patient think twice and then take action to resolve the matter.

First thing, If you don't have the control on your problem then let it go, and accept the problem and try to improve it. Be Calm and give your best without worrying and without taking stress and face the problem.

Avoid negative coping behaviors

It all depends on the type of "hard time" It could be:
Money
Employment
Health
Family
Love
Sex

Or a combination. The answer will be different for each situation

All thinges even bad , may be foung good in it , if you think good

That is the real point @Flora. If they care about me, they never hurt me everyday.

First they pretend that they care about us and then treat us like strangers.
This types of toxic people are very unworthy of your emotions.

If no one cares about you, you have not shown any emotion because if that person cares, they never hurt you.

I am strongly disagree with you @Nandkishore_Deopersad
