Idk - its a fairly short period of time, and she will probably be napping. For 30 minutes, maybe your mom could ask s neighbor to step in? I totally get it, because i would be the same as you - i have to totally stop my life, thats the only right thing to do - but i dont think thats how normal people handle things.
Eta - can you call your t and ask her opinion? Thats what i would probably do - have him talk me back to reality when im freaking out with indecision And stress.
