CoDPD & SPD have obvious similarities:
-Absolute need for independence
No, I'd rather be able to depend on someone, but it's extraordinarily difficult to find trustworthy people.
-Feeling completely choked when in a situation where you depend on another person.
No, just pessimistic about the other person's ability to help.
-Aversion for being "cared of" or "cared about". Ie: you are ok with "caring about others", but you don't want others to "care about you".
On the contrary, I welcome care (in its legitimate form: practical or material help) from anyone and everyone. In fact I could use more of it.
-Extremely low emotional lability. (ie: emotions are extremely hard to trigger, but can stay active a long time. Especially long term frustration.)
No, when something bothers me I do something about it...which typically results in new frustrations.
-Tendency to keep everything to yourself. Especially things that would require help from other people.
Yes, this fits.
-Tendency to mental rumination when frustrated, without actually doing anything about it other than thinking.
I used to be this way, but now I'm more inclined to shrug my shoulders and move on to something else.
-Inability to express emotions, especially anger.
No, I can do the anger thing competently. Then again, I've had good teachers.
-Aversion for emotions, particularly the emotions of other people.
Yes, this fits.
-Attempts to live a life devoid of emotions, especially stress related ones; but often fails since codepending is a major source of stress since you cannot control the codepended.
No, I attempt to live a life of happiness. One way to get closer to happiness is by avoiding codependency.
-Tend to express emotions IF and ONLY IF the trigger is related to a friend, especially the codepended. Ie: you couldn't care less about people bad mouthing you, but you do care if somebody bad mouthes your friends or your codepended.
I have no codependents so I can't answer this.
-Broken or inexistant sense of self. (This is said to be the cause of codependence.)
I have a deranged sense of self when I'm among other people, because in such situations I become a method actor.
-General feeling of purposelessness, feeling that one's existence is meaningless (and therefore use codependence to find a meaning in life and have a sense of purpose).
Purposeless, yes. But not related to codependence.
-Feeling empty (Codependence would be a way to try to "fill the void", by giving one's life meaning.)
Some feeling of emptiness. I think my life would only have more meaning if there could be a revaluation of most values (to paraphrase Nietzsche), and this won't happen.
-Generalised apathy and lethargy about things happening to one self. Apathy and lethargy only breaks when things are happening to somebody else.
Yes, but the "somebody else" isn't a part of the equation.
-Extreme aversion for "drama" and instabilities in one's life, especially emotional instabilities. Will do everything to have a completely stable life without any stressors; flat, stressless, emotionless, and quite probably colorless too.
Yes, this fits.
