It's a lot tougher than I thought it would be
Why did you expect it to be easier than this?
I won the lottery when I didn't expect to.
It can be difficult to navigate a big life change such as winning the lottery. If you don't feel capable of handling the situation on your own, you should get some help. A financial advisor would be a great person to turn to and get advice.
I'm not asking for help on how to buy what I want. I'm going to split it with my friends.
I think that it is kind of you to want to split it with friends. You should find someone to help you manage your money though, it is going to be helpful.
