Sweetie, I get like that, too.
And I am Vegan, as well.
I've had moments where I get all depressed and, for example, go grab me a Brisket BBQ sandwich and eat it like nothing
Or I'll eat a bunch of cheese or things containing processed white sugar....ugh
But, no matter what, I still can't ever eat pork, drink milk, or eat meat for days...I know way to much gross stuff, lol...but, I do get like that.
And I get where I just want to cry all the time.....
As a matter of fact I just went through one of these episodes a week ago....it lasted for almost 2-3 weeks for me...it was horrible.
I just kept getting soooooo sad and any little thing or nothing at all would make me cry.
I was just sad.....no real reason.
Eat things that make you happy naturally.....bananas, raw almonds, walnuts, leafy greens, oats, etc....or supplement.
(I don't do prescriptions...ever)
My episode started when I ran out of my magnesium.....
How long have you been a Vegan?
Do you supplement with B12?
Do you eat a lot of Kale?
If you are deficient in B12, Niacin, Magnesium, Calcium, Vitamin C, Vitamin D3, and a few others, you will become very severely depressed, get anxiety symptoms....and can even become catatonic in more serious cases.
