Lately I've been having the urge to ask for my part in the inheritance.
Why do you want to ask for your inheritance now?
Because lately I've been struggling with my finances. I feel my brother is to blame for it.
Your brother and your inheritance are separate issues. You should open a dialogue with your brother.
I honestly don't think it would do anything good.
I really do think this would be the best way to go about it. If you start getting a good relation with your brother then maybe he could help you deal with your financial struggles.
