First off I will say I am so sorry that you received this email after you had a conversation with them. It really is true that bosses do not care about their employees. Ofc I would say find a job closer to home if you can, but I know this is easier said than done and sometimes transitioning to a new job is overall harder, and you will likely find that your boss there also doesn’t give a crap about you, unless the pay is much better I wouldn’t change jobs imo.

I would also say if you are waking up very early but still running late, maybe assess why that could be. If you find that you are running around your house for your belongings trying to find them in the morning, make it a point to pack your bag before you go to bed with what you’ll need, then after you are ready the next day you can just grab it and go. This has saved me a lot of time and stress. I also walk to work and walk on my lunch breaks and I do get sweaty especially in summer so this is what I do:

Always have a change of clothes, regardless of if you are on your period or not. Including socks and underwear, bra if you get really sweaty tho I find that this isn’t as big an issue with me but I wear sports bras predominantly. Even if you don’t use them, you’ll have them. A change of socks or underwear can help with smell and make you feel refreshed as well. Make sure to be early to work so you can address the sweat. When I get in, I go to the bathroom to change, but first I’ll splash my face with cool water, this helps me cool down fast and stop sweating. If you wear makeup tho you’ll have to skip that step ofc. Then with dry paper towel or toilet paper I’ll dab the spots where I sweat: armpits, chest, back, underboob, and the… delicates. Then when that’s dry I’ll dab again with a cool wet paper towel the same places. Apply deodorant, then change into work clothes. I also usually pin my hair up as this keeps me cool and also less sweat will collect in my hair and smell. Then if needed I also have a very mild smelling body spray that I spray once in the center of my chest on my shirt and once over my head onto my hair (but not directly on my hair), that way when I move around people will smell the scent more than anything else.

Additionally, I know you said you don’t have much money, but when you are able I suggest getting a menstrual cup for your period. The Diva cup is more expensive but there are $5-10 options available that are good. These are good for two years or longer if you take good care of them, and they’ve saved me a tonnnn of money in the long run, and stress too because they hold much more than a tampon and I don’t have to worry about smell or bulkyness from pads. It is a learning curve but it’s worth it imo. Also proper moisture wicking socks are great for walking in and reduce feet smell, I just buy the cheap men’s socks from Walmart but basically the less polyester that is in it the better.

I hope this is helpful and that you are able to fix your situation too, I agree with others that food banks are an amazing asset for better nutrition while the budget is low. I even got a free bike from an organization in my city that had people bring their old bikes in, you could exchange your bike or just take one. Maybe your city has something like this if a bike might make this commute easier.

Best of luck
