I feel like I'm going to have a complete breakdown because of so much.

After my grandpa died things have been extremely hard. My mom ended up getting really bad covid from someone at my grandpa's funeral. She ended up in the hospital and ICU for awhile and although she's recovered enough by now that she in a nursing home to recover her strength I'm left having to deal with the rest of my family getting the house ready to sell by myself. There's so much to sort through. The stress is actually hurting me combined with the fact that eventually it'll be the last time I set foot in the house I spent a lot of my life in. Everything combined with not knowing if my mom will be strong enough to live in the place she owns and such a change in my routine and future routine being uncertainty makes me just want to curl up and sleep. I hate the uncertainty of everything and being pushed so much by my family. They think that I can easily deal with all the financial stuff because it looks like I'm not slowly losing my mind.
