Are you taking an antidepressant? My meds definitely help, along with high quality vitamins, supplements, eating healthy and exercising (usually a brisk 30 minute walk). It sounds like you're really fighting through this, which can be so hard to do. I recommend seeing a psychiatrist for meds and doing the other things I mentioned once you're up to it. Sorry about your cat but you should get a new kitten, too! I have gotten new kittens when I'm going through a rough patch and they're such good medicine! They can be so cute! Hope you're feeling better soon!
