Have you talked to your dr? Maybe he can help give you something to relax you till all this that you are dealing with calms down.
I find exercise works to help me calm down. I am not sure how it works ,but it works out the stress and emotions. My moods and sleep are better when I exert myself.
The other thing that has helped to calm me, is the herbal supplement St. John's Wort works like an anti-depressant but much weaker and less side effects. I would start with a little and see how you do. Kava Kava is another supplement to try.
You cannot take these if you are already on persciption anti-depressants. Check with dr if taking any meds, and read and research the herbs before trying them.
Here is the link on supplements, and St. John's Wort is the one I pulled up first, you can check other herbs on the site:
Do not mix Kava Kava and St. John's Wort. You would just take one or the other.
I have found this to work for me when I am anxious.
I hope this helps you some.
