Super Emotional (long post)

So im usually a cry baby but with things like movies about break ups, illness, death.. those kinda of things but I feel im being extra emotional...

I was at the store buying food to make dinner, I had just checked my account to see how much I had available (havent worked for 3 weeks) and when I was at the register the balance was higher than I had available. So I was trying to take out whatever wasnt necessary (2 things) the balance was still like $1 more than I had. So I was trying to get it down, then the lady behind me speaks up and tells the cashier, "Can you just add it to what I have?"

I was speechless and at the same time the cashier didnt understand so he wanted to know how much I had available and she said "No just add her balance to mine"

And the cashier said he didnt know what my remaining balance would be..

And she told him to charge my stuff with her stuff.

I was so embarrassed, and told her she didnt have to but she insisted it was fine.. I really didnt know what to say or do besides thank her.. her and her husband told me not to worry about it.. and as the cashier is scanning her stuff she asks the cashier to add in the stuff I had removed..

I quickly told her that was not necessary but she said it was no big deal.. I thanked her again and also had my 3 year old thank her ( he added a Merry Christmas) lol

We both left the store and as soon as I got in my car I just starter Balling my eyes out.

Not sure if its due to pregnancy since im early on or just being myself
