Been exactly where you are. Try not to let it dominate you, control you. Easier said than done I know. The fact that you are not alone and others have gone thru this does not necessarily make you feel any less alone. You may need some professional help to get a handle on things. A lot of us need some he from somewhere at least at some point. It can give you some much needed perspective. Try to slow down. You can deal with it positively. Only you can decide the answers will come from within you not outside you. It can be a burden you can turn into an asset.
From your last post it sounds like you already are in good thought process about it all.
