What do you do for stress relief / easing anxiety?

Hubby & I have been TTC for going on 5 months now & I feel like I'm going crazy (not about getting pregnant right away or anything). Long story short, my husband has mental illnesses that make things a little difficult. If he forgets his meds for a day or 2 or a few, he gets weird. He has had phases where he doesn't feel emotions (happy, sad, angry, anything...) & has told me he doesn't know if he is in love with me & has been suicidal. It is so hard to deal with at times, but I love him enough that I will. He had a big mental break down last summer & it was the worst I have seen in the 9 years I have known him & I thought we were going to divorce, because it was too much. Things are better now & I typically remind him & watch him take his meds & he is a lot more stable, but now I have this crazy anxiety & I freak out at the slightest thing & get so worked up that I create all these issues in my head that aren't even there. I have literally worried myself sick. I'm trying to get in to see a psych to see if they can help me, but just wondering if maybe anyone has good remedies that help them calm their nerves that don't require taking meds. Also I am 2 days late so its possible some of it could be pregnancy hormones, but I really don't know.
