So for me, I read, play cute video games like Animal Crossing, Fantasy Life, Harvest Moon, etc.; go on nature walks and take pictures, or take a hot bath in a candle-lit room. The key is to get your mind off of your daily struggles.
At the same time, I think your schedule is unsustainable and something has got to change.
Being a preschool teacher is hard AF! Toddlers are busy little people who love pushing buttons! I worked in retail hell for four of the years I was in school (it took me 8 years to get my BA because I have a learning disability) and that’s hard AF too! Crazy customers! Stupid managers! Good times.
And you’re in school on top of that?! How many units are you taking? I can’t imagine being able to study much when you’re working a bagillion hours on your feet. I worked 30 hours a week max while in school and simplified my lifestyle (had a Nokia dumb phone, no cable, drove a cheap used car, cooked all my food/brewed my own caffeine beverages, got my hair cut for $5 at the local beauty school). Can you cut back to just the toddler wrangling job?
I planned a simple budget no-frills wedding while I was finishing up my AA (9 units, 30 hours of work a week, much more manageable than your schedule). Tips:
People create the most drama so try to limit the number of people involved. Invite only immediate family and any friends who played an active role in you getting together (e.g. DH and I were elaborately set up by my college friends so they had to be there). I had 30 people in all but could have cut the list down to 14 if I needed to.
Choose the path of least resistance for everything. I chose impossible to screw up colors (black, white, marzipan, and cotton candy pink) so I could mindlessly coordinate BM looks, bouquet flowers, cake, and table centerpieces instead of obsessing over whether or not something would clash. I had my Bridal Party wear their already-owned LBDs so they’d save money and I wouldn’t need to deal with dress drama, and I bought them pink shrugs and necklaces to create a cohesive look.
Money is the other main source of drama so cut corners. Your guests only care about the food, the booze, the comfort level of the venue, and maybe the music. Make sure the food is filling and tasty and you’ve got a great playlist and you are good to go!
Guests don’t care about your dress, so buy the cheapest one you can live with. They don’t care about your flowers or your decorations or your invites or how pretty your cake is, so keep them simple or skip them altogether. DH and I used candles and rose petal centerpieces and had a super basic but delicious cake. I’ve had friends DiY cute paper flowers for pennies (I’ve got no patience for that myself, though), or use potted orchids or succulents.
I hope I don’t sound like I’m pontificating too much! Just want to keep you from going crazy.
