BP2 and BPD

hi all, i have bipolar 2, i’ve been taking lamictal for a year now and it has helped tremendously!!! i feel like my mood has shifted completely and is the most stabilized it’s been since i was a child. However, i find that there are “triggers” or tone of voice for example that will send me into spirals or detach but are separate from my mood. one is an uncontrollable mood swing/ hypomania that have a duration and again, out of my control- the other is spontaneous and brought on by something else. i know what BPD is as i was a pre med psych student … i do have ptsd that im working through in CPT therapy but these quick switches are something ive always experienced. Im 24 and have SH since my trauma began and still reach for that coping in the case of an event or trigger as a way to detach

i was told i should ask my new psych (my current/ old one is moving out of state so i will be transferred to a new clinician) if having bpd is a possibility with my bipolar

not looking for a medical diagnosis or “ask your psych” but advice

does anybody else experience BPD and Bipolar and if so does this sound like something you’ve experienced? i don’t self diagnose, in fact, i hate it and hate when others do, but want to see if this is something i should bring up as it can affect my day to day
