Sounds like you are having a hard time. I know it feels like life in general is overwhelming, but most likely some particular problem/disappointment has come along and acted like the straw on the camel's back. Try to think what that might be.

I think most of us who get to feeling like you do (and I have) are lacking in having a good source of moral support. If there is someone in your life that you can talk to, try to reach out. If not, it's hard to do a lot about that when you feel as bad as you do.

There might be something major in your life that needs to be changed. Ask yourself what things in your life could you possibly change. Maybe you need to take a couple days off from work. I know that doesn't solve major problems, but it can give you a break that you may really need.

We all feel best when we have some sort of a long range plan for ourselves that we believe in. Coming up with that can be powerful hard to do, but you've probably done it before.

I hope you feel better. It's hard to feel so awfully weighed down. Keep posting about how this is going for you.
