So I was diagnosed a couple weeks ago along with MDD with anxious distress but I've also been in a 5 year long cycle of addiction. Im just reaching out to see if others can relate considering i've been feeling down about myself lately about this topic

After lurking here and other forums I've noticed that most posts regarding substance abuse are usually about weed and sometimes pills. Personally, I find it hard to relate to a post about weed addiction since obviously what I use is much worse and has such a bad image to it, like damn of all the drugs I could have gotten addicted it had to be this one lmao. 
So I just wanted to ask some questions hoping I'm not alone. 

Has anyone with BPD struggled/is struggling with something harder? I'm talking about hard street drugs made in a dark worn down basement with every chemical lol. If so, how did it affect your BPD? Why did you start using? Foreseeable plans for sobriety/currently sober??
