Whatever you're suffering from, the weed on a daily basis may be obscuring or exacerbating your symptoms. I don't know anything about BPD, but I've heard of psychiatrists insisting that a patient quit weed for at least a month so that they can get a clearer picture of the patient's underlying condition and make a diagnosis. One of my doctors, who after completing his medical degree in Canada went on to complete a second doctorate in Chinese medicine, was convinced that my heavy (state-licensed) weed intake was the root of all of my problems. I will be stopping weed altogether in 2017 due to practical and financial considerations, so I hope that he was right.
