I appreciate your concerns and asking on HCM.
Based on the history I would suggest the following:
1. I presume that potpouri is a mixture of some drugs,drugs tend to interfere with our mood and it is vice versa as well. Once one is depressed it can lead to use of drugs. However the symptoms you have mentioned appear to be a combination of
anxiety and
depression and you need further evaluation to ascertain some diagnosis.
2. You can involve yourself in activities that interest you like any hobby.
3. Take out time and practice progressive muscular relaxation exercises they help to ease out the stress/
4. Apply self help Cognitive
behavioral therapy on yourself.
5. Reduce caffeine intake, beverages and
smoking as they increase anxiety.
6. Practice deep breathing exercises for controlling anxiety.
I hope you find this helpful. Have a nice time.
