How Much Longer???

So, it's been 6 weeks since my mom passed away...we still don't know the cause of her death. That's a hard thing to deal with. I know that my mom had chronic pain, but it shouldn't have killed her. To top it off, she was only 46 years old!!! There had been a few visits in the last 8 months of her life where the doctors said that she overdosed (she was on some potent pain killers), but I really don't think that was the case, no one in my family believes that. There was no reason for a 46 year old woman to die. When they checked on her medications after she died, they found that they were all accounted for. How much longer do I have to wait to find out how my mom died??

Part of me wants to know, but part of me doesn't. If they say that she overdosed, I think I will have a hard time accepting it because I knew that as much as my mom longed to go "home," she knew that she had 3 daughters and 4 grandchildren counting on her, not to mention COUNTLESS other family members. I pray that God would work in this situation, make the best of it, bring some good out of it (I know it is possible).
