mixing pharms with shrooms wasnt a brilliant idea.
inexperience and panic attack sound right to me.
IMO, mixing drugs that cause mild to sever hallucinations with booze/anti-depressants is not a smart or fun thing to do. I would ask myself..."self...what is it you are looking for in a high? if you intentions are to get so fucked up you cant remember anything this could be a symptom of your surroundings/life. If you intentions are to have fun you should educate yourself with the drugs you want to do and learn how to do them safely.
Be safe.
