I’ve been struggling for the last few weeks (especially today) with thoughts that the person I’m seeing is also seeing other people. Part of the issue is obviously that I’ve fixated on the idea and am going over small details again and again and not knowing what to do about the situation &amp; dealing with extreme feelings of frustration, confusion and anxiety. The other part of the issue is that I’m becoming distressed as I can’t figure out if I’m being rational or if it’s my bpd ‘talking’ (I’m not sure if that makes sense). I don’t know whether or not to believe that it is a gut instinct or if I’m self sabotaging and creating this paranoia myself. I’m getting very upset trying to figure out if I believe my own thoughts.
