I share traits with other personality disorders. Here are some of my symptoms:

1. I feel little or no remorse.
2. I have a very hard time apologizing, and feel like it is a huge sacrifice to do so.
3. I am extremely sensitive to any kind of criticism.
4. I think I'm always right.
5. I lie about almost everything, except this post, because I'm trying to figure out what's wrong with me.
6. I am prone to self-reflection, and am very self-aware.
7. I become angry when people show emotion, and will secretly judge and ridicule them for being weak.
8. I despise myself when I show emotion.
9. Secretly, I have really low self-worth.
10. I hate most human beings for being human, and think of them as beneath me.
11. I am very judgmental, but come across as non-judgmental.
12. I come across as shy, withdrawn, and socially awkward.
13. I think I am a hypocrite in almost everything I do, because my beliefs conflict with my actions.

Here are the BPD traits I do have:

1. Chronic feeling of emptiness
2. Constantly shifting sense of self
3. Impulsivity
4. Intense anger and rage
5. All of my relationships are unstable and lead to inevitable failure
6. I become even more unstable when I'm in a relationship
7. I'm a reckless driver.
8. Splitting
9. I'm often irritable
10. Have struggled with an eating disorder throughout my life (ED cited as often being comorbid with BPD)

I also share traits with people with AvPD:

1. Avoid people because I'm worried they're going to say something to hurt me or upset me.
2. Intense fear of social situations.
3. No close friends.
4. Haven't been in a relationship since 2013, and never will again.
5. Intense fear of criticism or rejection.

I feel like I might just have Mixed Personality Disorder, about which there is very little documentation.
