I was wondering if withdrawals could heighten or even cause the development of BPD.

I went off my anti depressants and anti anxiety meds from the start of 2017 to the start of 2018, so a little over a year unmedicated. Mostly this was done out of fear that when I was living on my own I wouldn’t know how to cope without my medication if I wasn’t able to access it. During that time, I began to develop new symptoms and worsened symptoms that had been there from the start. Since it coincided with the usual age people develop BPD, I’m not sure if this is just a coincidence, medication disuse exacerbated my issues, or it almost completely caused my development of BPD symptoms. If anyone has any ideas lemme know. I want to present everything I’m learning to my therapist.
