Sorry that you felt like people jumped on you, but their concerns were genuine and well-founded. Benzo withdrawal is no joke and can leave you with permanent neurological damage. And if your mother has a history of klonopin addiction you are at elevated risk of becoming addicted yourself. All that being said, it also sounds like you have real PTSD and anxiety issues and that SSRIs weren't addressing them. So if you have decided the rewards outweigh the risks, here are some thoughts from the Greatest Mind the Darknet Has Ever KnownTM ).
You need a long-lasting benzo for generalized anxiety. The Grand Wizard would recommend starting out with 5mg of diazepam (Valium) or .5mg of clonazepam (Klonopin) two or three times a day. (Morning and bedtime or morning, lunch and bedtime as you prefer). If that doesn't work go up to 1mg. Alprazolam (Xanax) is really best for breakthrough anxiety -- sudden panic attacks rather than ongoing continual worry. Take one as needed, no more than 2 or 3 times a day: 1/4 of a bar or .5mg should do the trick, as alprazolam is far more potent than people realize.
Whatever you do, try to use as little klonopin and xanax as possible. Try to learn coping mechanisms and alternative strategies. (You may also want to attend a few Al-Anon or NA sessions to talk about your parents' drug issues: benzos work best as an adjunct to talk therapy, not as a cure-all).
The Grand Wizard has to repeat again that benzos are highly addictive and benzo withdrawal can kill you. But we also are assuming you know what's going on inside your own head. If you are capable of using them responsibly, benzos will definitely help with your anxiety issues. Instead of lecturing you, the Grand Wizard is going to treat you like an adult and give you such information as he has on the subject. What you do with it is up to you.
