Social media can have different effects of students depending on the person. Whether it's positive , for example posting a photo of a dog or cute photo can improve a person's self worth and interacting with friends can be a huge important role in making a student feel like they have a purpose .

For example posting a photo of ones self, and having a bully comment something mean, can make a person's self worth and self esteem decline.
It all depends on the maturity level and what they are capable of their own mental health understanding !
