Suspecting that I might be BPD

I was much more emotionally sensitive and generally emotive than other boys around me, I would start tearing up if I heard that someone got bullied in my class or seeing news about african children starving, and always had a softer demeanor, which earned teasing in the likes of "sissy", "pussy", "milk" (turkish term for soft boys ) which I learned to hide as I hit puberty

I feel emotions very intensely, small amount of happiness becomes joy and a little bit of sadness becomes full blown grief.

I feel constant emotional pain and I am very sentimental about the past and constantly play emotional scenarios in my head about sad things happening to my relatives or having happy moments with my favorite person (which results in me tearing up)

I am generally stable but this month I risked my life and homeless in order to meet my FP and did alot of sudden changes like relocate into another country and change my sexuality and behavior and identity...I attempted suicide in the hotel because my FP told me they dont want me anymore.

I can't tell if this is C-PTSD or BPD though, I've been severely abused by my parents and peers as a child and I've sadistically tormented people which resulted in massive amounts of guilt.

What do you guys think? I'm down to provide more details if you wish.

I was diagnosed with BPD by a psychiatrist and I have similar experiences as you.
I have extreme emotions even from seeing my mom's cat. He is now 16 years old and whenever I see him I feel teary because animals live less than people and I don't know how my mom will be without him.
I have extreme fear that people I know will die or abandon me. I was hospitalized because I wanted to commit suicide in order to die first. My parents are older than me, obviously, so I will live longer than them. I do have friends who are my age but I am concerned that they don't need me because they will be busy with their kids or nephews, family. I feel like no one will agree to have kids with me.

I feel very ugly and not interesting enough, this again leads to fears of abandonment, because I am not sure anyone enjoys talking to me.

I am dating someone but I always have thoughts that he can find someone smarter. He is in computer science and I feel like he needs to be with one of his female friends who have PhDs in computer science.

Many times I had panic attacks if my boyfriend did not pick up the phone. Also I thought he was trying to get rid of me or that he would change the lock on the door.

I often feel extremely lonely and that causes great emotional pain.

After hearing all these symptoms, the psychiatrist said he is certain that I have BPD. I was diagnosed very recently.
