The advice I give everyone is stop taking drugs ... at least for a while. See if the symptoms moderate. For me, weed really makes my visuals intolerable so I don't touch it. Every once in a great while I give it a try and it's never pleasant. You did one dose of LSA or did you do other hallucinogenic substances as well? If you've only dosed once you may have a good chance of having your symptoms clear up but it might take a while. If you're having issues with anxiety, I can't recommend mindful meditation enough. Good medicine. I don't take any prescription medication so I can't comment on that. Hang in there!
