There are many kinds of depression. Situational is one. You will get the same symptoms regardless of the type or how long it lasts. If you do not handle the stress emotionally, it takes it out on your body. If you continue to lose weight, it may be a good idea to visit your physician to help you thru temporarily.
Do you have a psychiatrist at all? It sounds like you are internalizing your feelings, and you body is showing it instead. Having support is the best thing for you. Are on any meds for you panic attacks and feelings of depression. It's okay to ask for help, there are many meds which can help, especially since you've had a history of panic attacks, it's a miserable place to be in. If you don't have a pdoc, see if you can get a referral, but I would suggest you see your regular doctor anyways.
Hello, well i think that your weight loss is obviously due to nerves and stress. Stress can do many things to your body, including weight loss. Because of your panic attacks, your body is in overdrive all the time and i believe that could be the reason why ur losing weight. Im sorry that ur going through a divorce. Been there done that. Try some high calorie milk shakes or ensure i believe is loaded with calories. Good luck.
