Social anxiety or psychotic symptoms due weed?

Past june I had a psychotic episode from weed. I quit smoking for five months. I started smoking again but only one or two times a week. And most of the time the experience was pretty bad. While on weed I had massive anxiety; a panic attack that causes dpdr for five days; paranoia; thinking I'm hearing strange sounds; my hands and legs shake so much that people around me notice; or that people hate me secretly and they was sending hints for me; or people are talking about me behind my back. I once smoked in public and had the feeling that people was staring and laughing at me; also i thought they were saying my name. I was two weeks without smoking and then yesterday I smoke again and it was a bad experience. I feel like if I keep smoking I'm going to have another episode. I'm quitting smoking for good. My question is: am I having psychotic symptons or this is just social anxiety worsened by weed? I can have the insight that it's all in my head but this kind of feelings is very strong and scares me.
