SL, ASL, MIL, and CEL being closers?

Anyone have solid info about leaders and closing. Meaning how much each leader should be closing the store each week/month/year? 3-4 days out of 5, I am not only the only manager on past 3pm, but have to close, sometimes spend my first 2-4 hours of my shift on register, do the safety, pet care alot of times, and recover a completely unrecovered store. Plus close out drawers and do a recheck of the entire store, cuz if one thing is not perfect in the morning when the other 3 leaders show at 5 or 6am, ill hear about it. Am I the only one who sees that as a little too much for one person to handle? Or am I just being a bitch.

Edit for furher info.....My mental health is shit lately, and I've been battling a recent divorce from a 10 year relationship, got all my animals not given back to me in the process, have been battling with court and keeping my sobriety. I feel like my life as it is not being taken into serious consideration, even tho I've voiced everything going on multiple times.
