It's ok for you to tell how you feel on here. It's probably good therapy to know your not alone. I think like some of the other post....we all go through this at one time or another in our life. Some is worse than others. I've been down to some extent over the past year because of so many changes in my life that i don't like. I'm not one that accepts change well.
But i know in the back of my mind God will get me through this like he always does.
Also i agree with someone else posted to find something positive to do. That will help because you don't focus on the negative as much. Hang in there you'll make it. It's just really tough sometimes and as I type this I know words seems inadequate, but on YT that's the only way we can help each other is through words.
Hope this helps some......and i'll keep you in my prayers.
