Hurry up and Wait

I want to know why in life every thing seems to be a "hurry up" or "wait" situation?

Right now several of my blogg friends know I have not been feeling well. I seem to be having some severe physical problems that, bless there little hearts, also trigger some of my mental issues.

I have been checking into what opions I have and it seems like I'm spinning out of control.

Fact: I'm not healthy enough to continue what I'm doing.

1. Should I just "down size" and work less?
2. Should I push the disability issues?
3. Do I just work until I fall over dead?
4. Do I let my company fire me?
5. Do I resign, because I just can no longer do what is required?

More Facts:

1. I have been "ill" more in the last 6 months than I have since I started with the company 18 years ago.
2. The company I work for is "very big business" and doesn't care about the employees. ( this has added to the already stressful situation)
3. Disability pay would drop my income about $400.00 per month and I barely make it now!
4. My youngest son is a severe agoraphobic and has not been able to work in over 2 years. I'm trying to support both of us.
5. My son just applied for disability to help with his medical bills and currently has zero income.

I have several questions, but I'm getting more over whelmed by the moment. I using my short term sick benifits right now at work, because the is no way I can work full time right now. If anyone has been throught this and has any suggestions , I sure would like to know your ideas on what the best steps are.
