Hi IWBT,
You seem to be very sensible to any supplement or drug. So, I feel you should go very slowly, introducing/testing only one at a time, and always starting with very low dosage.
For example, testing only omega-3 ( fish oil), and only one capsule, every 2 days or every day, for at least a couple of weeks, and see what it does.
Do you feel sleepy after meals? Does alcohol make you sleepy after even only one serving? Are the white of your eyes often tainted with greenish/yellowish color, more visible under the eyelids ? Is your urine dark? If so, you may have a sluggish, slow liver, and should slowly learn about liver detox. First step is to drink more source/clean water ( For more detailed info on liver detox, see

Also, you seem to have a very reactive nervous system ( just like I do...). What helps me the most with this is daily meditation/slow breathing exercise. Only 5 to 10 mins a day will show a huge difference after about 6 to 8 weeks. Meditation does not have to be complicated. Just sitting, relaxed, eye closed, and breathing slowly, and observe breathing. And bringing back attention to breath, whenever one becomes aware that he has not just observed silently a train of passing thoughts, but have jumped on it and have followed it. When you get the hang of it, you observe passing thoughts like when you are in a subway station - trains pass by, but you stay there, quiet and still, on the platform, and let them come and go. Yoga and Tai Chi are helping too, in calming the nervous system , and reprogramming your body/mind in being less reactive, more detached, and calm. And they do not have the side effects of anti-depressant drugs ( which may be essential for those who are diagnosed with a depression and really need an anti-depressant, but that does not seem to be your case).
I hope this will help you.
