I don't know how aged my Heating and A/C filter is

My mind is on anything however my home responsibilities and chores right now. I just lost my cousin who I grew up with and considered to be a second brother. My friend and I hung out together constantly in the years since we were both little teenagers, he was always a close friend and somebody enjoyed spending time with; Since my cousin didn’t have any siblings himself, he was like another brother to me. His parents were often working when they needed to be home as well. So he would spend time at my property instead of being left alone in his house. When I heard that he had died in her accident, it devastated me. I was completely exasperated by the whole experience. It was bewildering to me when it happened and I still don’t know if I’m going to be over it anytime soon. So because of all of my grief, it’s hard for me to know of my responsibilities and chores. I had forgotten to update my cooling system filter for 3 months straight. In my region it gets so dusty that you need to update your cooling system filter every 4 to 6 weeks. These are central things you need to do to make sure that your cooling system filter does not get too jammed. I don’t even know exactly how aged this cooling system filter is, that has how terrible the situation has become for me. I don’t even know what I’m going to do with all of my forgetfulness as a result of my grief. I don’t want to cause my cooling system to split down because I’m in so much mental pain.
