Not sure where to post this....

Hi all. I'm just looking for some advice on how to tell my 2 year old son that his uncle won't be at his birthday or at grandma and grandpa's when he goes to visit anymore.

Some background: my hubby and his brother are adopted by their parents from birth. My brother in law has diabetes and very self destructive behavior. Although when we revealed we were pregnant with our son he seemed to get himself under control and went back to school and took excellent care of himself.

Fast forward to Halloween 2015. Got a call from my MIL asking if we had seen or heard from BIL because he left a suicide note and left his dog (his baby) at their house. My hubby went out with their dad and searched for hours for him and then the police called to say they had him and were taking him to the mental health facility. Hubby and FIL went to make sure he was ok and he stayed in there for a month. He was released and medicated but a week or so after new years we've noticed his behavior going back to the self harming and self destructive ways.

Well yesterday morning BIL called my hubby asking him to call their dad and let him know his car was toast. Prompting red flags with my hubby he called his parents who left their jobs and went home to find my BIL destroying their house and cutting himself. So they called the police and had him arrested and committed under the mental health act. When my in laws got to the hospital his blood sugar was 37 when it should have been between 4-7.

So now our sons birthday party is next weekend and he's asking if uncle ry will be there. How do we tell a 2 year old that his uncle won't be able to be around him for a while.

Sorry it turned into more of a rant!
