No it is just cramping from the cycle when the layer coming off meaning your period or you could have cyst on your ovary‘s causing that pain
Me personally, from what I've seen it would probably be B. I myself used to keep my emotions private and it caused a bit of depression. Trying to be like one's peers usually means that they are not content with who they are and wish to be better by being like someone who is liked by more people.
Hope this answer helps! feel free to ask any additional questions :)
