Do I have BPD (Borderline Personality Disorder)?

I am a 21 yr old female who goes to school fulltime and works fulltime. I've always thought that something was different about me compared to my friends and peers. On average I'd say I have 2-5 mood swings a day, depending on stress levels n such. I thought that I was getting better but I just realized that I've only gotten better at making it look like I'm normal. I've reached the point of just not being able to handle it. I'm not suicidal or anything,I just feel empty a lot. I'm extremely sensitive to other peoples body language and slightest change in facial expressions. I can get irrationally impulsive and/or irritable, randomly. I keep myself pretty busy but nothing seems to satisfy except things that are extremely stimulating. Like, going to Raves, something about the loud music, lights and dancing helps clear my head (temporarily). Also, makes me feel good. Its hard to have a significant other because I like them one day then the next day Im creeped out by them. When I attempt to have one Ill get insanely attached, and when that happens I feel like I have to be around that person 24/7, so I try and avoid it. I feel like my head is so jam packed with thoughts its going to explode. Anyone have any advice??
