Hi, I'm a 17 year old from the UK

I feel like I might have BPD but I'm not even totally sure so I'm not going to say anything but I do relate to some of the traits/symptoms. I'm quite sensitive and small mishaps or anything can lead to increased emotion and reactions. My emotions can shift quite often. Between sad/anger/anxiety. I have engaged in self-harm, also the explosive anger aspect. I have a short fuse definitely. And also chronic emptiness feelings. And mood swings- but I might have already mentioned that, anywayyy I don't relate to everything but I relate to some of it- i haven't really known until now but im not gonna say I do have it right now-

Any help is appreciated.
