From what I have read online and through health magazines, the answer is yes--you can end up compromising your immune system because of stress/anxiety. My mom was in a terribly awful marriage. My dad was verbally abusive for 26 years to her, and she was always stressed out, to the point of it being ridiculous. She got sick a lot more (just with everyday stuff) back when she was married to him. She was constantly getting horrible migraines (saw lights, her vision was blurry, had to be in a completely blackened room). After the divorce 3 years ago, she doesn't get sick nearly as much. It's such a drastic difference.

Yes it can damage your health. If you start getting bad stress it will hurt your diet and you can get ulcers and all that.. Try to relax and something that relaxes you. I could go on forever about stress hurting you but the face is it does.
