I've been sad..... Not changing clothes for a few days, neglecting appearance and sometimes drinking and smoking marijuana and potpourri.
Your question? Not sure what your question is, but you seem aware that these behaviors are of concern or you wouldn't be posting them. Please discuss with your psychiatrist and therapist. Abusing substances will not help -- including "potpourri." it's likely sprayed with something that mimics thc, but in unknown quantity & identity.
