Safer way to get relief from stress.

I have dropped my career as a graphic designer after my husband has been transferred to Boston who is a corporate executive. The situation changed when John lost his job in a corporate reorganization. My children are in high school now and they can take care of themselves. I would really love to start my job again and I think it would be financially sensible. My husband does not agree with me and this is causing stress in my family life. He has starting taking a few medicines without a physician’s consultation. Can anyone suggest a better and safe way? All tips and suggestions are welcome.
