I've had moments where I cry in the bathroom, or if I just can't take it, I've cried in public places. Dealing with a loved one with an addiction is hard enough, but throw other family with health issues into the mix and it gets pretty tough. You have to remind yourself that your stress isn't forever, and do something that you love, and make sure you make time for it. I like to zone out on a good book or a good movie, something that makes me stop thinking about everything that's going on that is a stressor, if only for an hour or two. If you feel like it's too much, definitely go to a therapist. You don't want the stress to end up making you sick.
