I crave pain to make up for what I don't have
Do you have a reason that you enjoy the pain?
That's just the way I am.
Have you tried talking to someone about it? It might help you not crave pain and crave more positive experiences.
Nope, I'm going to get used to it on my own.
You shouldn't have to get used to it though. You're encouraged to get help if you find yourself craving pain. There could be reasons why you are experiencing this but you need to find out why.
