School is the gateway to my bad mental health ???

Okay ik this is a weird way to start off my first blog but I HAVE to talk about this. I started school last week and ever since then, my mental health has plummeted. All of these terrible thoughts seem to flood my head the second school starts to roll back around and it's so weird to me because during the summer I felt perfectly fine. Now I won't say that my mental health was the best during the summer, there's still a few things that have stuck with me no matter the season. It's just odd for things to feel soooooo terrible once school starts. I really wanna know if i'm the only one who deals with this type of stuff.
