Hello, 4 months ago i had an lsd bad trip combined with mdma. I was quite experienced on acid so i thought i could handle a large dose. But things went wrong and i had a bad trip. After that i have a constant pressure in my head that doesn t go away. Only reduces or increases in terms of intensity. I am fine otherwise but when i do some psychedelics including weed i get panic attacks. Please help me get back to myself and enjoy the drugs like before. Ive tried all the benzodiazepines like clonazepam and xanax but nothing seems to have worked. Please help.
