I might have BPD?

Well, if you read the title you understand what this is about. But I don't know what to do so I was wondering if anyone who has BPD thinks it sound likely. I've had *some* anger issues since I was really little--I would throw a fit almost twice a day, before an after school. In kindergarden there were many times when I was still crying on the car ride to my school. In 4th grade my parents decided it was too much and I went to a therapist where I did Cognitive Behavorial Therapy for 2 years. I hated it because it felt like I was in trouble and I was embarrased that I needed it. I didn't tell any of my friends and I still haven't, which brings me to my next point. I don't trust many people. I have one person who is the closest person to me, but I still don't tell them everything and they don't know about my therapy. Then I have one other person who I mostly trust and everyone else I secretly hate. I haven't known these people for very long, in 3rd grade I was friends with some people, then in 4th grade I was 'in' with the popular kids, then they ditched me and in 5th grade I was a loner. At recess I would sit and read my book alone, and I got annoyed when people tried to play with me. Finally I gave in but a lot of times I got annoyed with the people I played with and wanted to just get away from them. I would hate them for a day then I'd be fine. In 6th grade I finally had a stable friend group and it's stayed like that ever since, but there are still days where I'm nicer to my 'friends' and some days I won't talk to them. Or, I'm friends with someone for a week and then I decide that since they did one thing wrong they are a jerk and I shouldn't talk to them. I also can't order for myself at restaurants, I make my parents do it for me. One time, my dad didn't know what I wanted to he told me I had to order but I couldn't talk and I started crying. I just want to know what's wrong with me--thanks for taking the time to read this.
