Think I might be suffering from borderline personality disorder

For the past two or three weeks now I have been feeling very emotional with my thoughts taking control, it's quite exhausting and I stay up most the night as I cannot "shut off" and when I do I usually wake up at 1-3am not being able to go back to sleep for a couple hours. This is quite bad as I am still attending school and even worse as I'm doing work placement. Anyway I feel like I've had some sort of personality disorder as I get very attached to people (abandonment issues) even if I don't know them too well, also used to suffer with anger issues in the past and at times I can feel so energetic it even effects my speech. I'm pretty sure I've just been ignoring the issues in the past and let all my emotions and just everything build up untill recently it feels like everything has just collapsed at once all these emotions and thoughts running through my head is exhausting and I just put on a mask to hide everything from everyone.
