Periods are sometimes painful, and when they're not they're still uncomfortable. Also they make me depressed, there's only one week of the month that I'm feeling fine, so that sucks.
For tips, I don't know if they will all work because every period works differently, but I can tell what helps ME feel better and if you ever think you need to do the same well at least you'll be aware (:
1- When I'm really sick and everything hurts, it all goes away when I throw up and then sleep. You need to do both though, or else it doesn't work unfortunately ):
2- I've seen on the internet that eating chocolate or ice cream helps with the pain. It does, but only while you're eating, and when you stop it all comes back (I'm not sure if it comes back worse or if it's just because my body doesn't want it to be back). I don't know if it's just me, you can try it if you want, but I don't suggest it because it's really not fun.
3- Like @Yue_ said, warm things are great. Wether it's food or objects, even if it won't make a miracle, it'll help you feel a bit better.
4- This one is a bit dark, and also not very common, so you can just to ignore it or skip it altogether if you don't think it's your case. If you get suicidal thoughts, just tell yourself to wait a week. Usually it leaves with the period, even if you stay sad. I don't really know what else to say about this to make it seem less awkward, I actually didn't even want to write this part. But I feel like it's a good tip to know just in case you happen to be one of the few people like that.
I can't think of anything else at the moment, maybe I'll write again later if I remember other things.
