Hi!
I was recently diagnosed with Bipolar and "mild" anxiety and BPD. Mild in such form that I scored high/very high on certain things but overall I am barely under the threshold.
On the test (it was german) which was a self assesment (borderline personality inventory) I rated high on "primitive defense mechanismen with object realtions" (*Primitive Abwehrmechanismen und Objektbeziehungen) and slightly high at "fear of closness" (Angst vor nähe) and high on "false reality check"  (mangelhafte realitätsprüfung)

And it was kinda an eye opener because I see myself living with this defense mechanisms. I think what I do most is splitting and projecting. I find myself thinking to know something what a person does and then I indulge in this negative hat thinking. Or I do things and then project these fears on others. I have internal dialogues and then boom im mad at them. I have this, to a degree, under control. but it is really hard. What can I do against this?

examples:
(most of these are from my "relationship" with a girl. kinda-gf)
When she is ignoring my text because she is busy i go into "hatemode" and think i deserve someone better, i dont love her and she does not love. when she answers everything is alright.
we met on tinder. so when feel really neglected, ignored, unloved i go on tinder and start swiping around (have never messaged somebody) but when she is out i hav always the fear that she is going to leave me for someone else. probably the fear because we are not really in a relationship (she does not want one - stated this from the beginning) and recently when i asked her if she loved me she changed subject (she told me before that she loved me).
