Should I smoke weed again

I smoked a pure joint and after I could feel it had worn off I started feeling like Im in a dream and this feeling has persisted since then and is starting to go away now. I also take mirtazapine for anxiety and depression and weed has been helping me for quite a while. But I'm used to smoking joints mixed with tobacco and not ones with all weed in. I'm now feeling anxious even thinking about smoking a joint. What should I do because I dont want to quit smoking weed.
