Feeling like going crazy after meditation

I have been practicing meditation for a month or so, but laying down because I could not do it sitting up. It did feel nice and made me feel more relaxed and present overall. Then three times I did a sitting mediation, literally the most basic simple stuff for beginners. It felt great in the moment of meditation, but afterwards, each time I would feel this unrest, anxiety even worse than before. Two days ago I did it for the third time, got the same strange uneasy feeling, like I am not myself. So stupidly I got drunk and then high on weed, and had the worst derealization panic attack ever, lasted for about an hour and a half. Since then, the derealization is getting worse, I am lucid and coherent, but have things feeling like - I am an alien come down to earth and I kinda get how things work but have no idea how to feel about anything or think about anything. It's like everything about my life seems far away in the distance, idk its such a strange feeling its hard to explain. Did anyone have even similar experience to this and if so I would really appreciate any advice on how to deal with this. Even when I stop panicking about it, when I calm down my baseline is that same lost feeling and its just too much
