I feel your pain. I have isolated myself too. I was forced to leave my job due to it's closing but it has made me much worse. I know it's hard to cope but if you leave your job you'll isolate yourself in your home and maybe not even getting out of bed. Maybe you could use that extra hour that your sitting in your car and get some exersize walking. Look at it this way, your half way there by just being up and out of your house. Don't give up on you.
