Where to Apply Suggestions Needed

Age 63, in Northern ID, no longer able to work at throwing 50 lb. around, little experience and needing good income what do I turn to??? Chip truck? End or belly dump? (Towing doesn't seem to pay) Equipment rental places? Shouldn't I have more experience for wide loads? Boom truck (where to look) Special endorsement considerations (If so, is there an experience factor and , if so, how to get it)? OTR or (perish the thought) go back to Swift? (Being away from home was becoming a challenge to my marriage but might risk it if absolutely necessary)? Other?
Background:
Got my CDL-A at Swift Academy, Lewiston, Jul 07 (it was great), followed by 6-week mentor program (sucked) and then Wal-Mart dedicated solo (2Wks - good deal in general, dry vans & Reefer). Night driving in the rain along city streets and State Hwy exits resulted in high stress, late deliveries and glasses. - I was told that I couldn't get day-time only runs while waiting for the glasses, and that being late again would result in termination. Even after showing them at Swift my eye prescription, I was told that my problem wasn't with vision but inadequate pretrip planning. - Why continue doing the same thing, expecting different results? The risk was ending up terminated or, much worse having an accident and hurting someone. - Now, doctor just told me that I herniated an old surgery incision pulling triple rail chains in and out of side compartment (because there was no chain rack). Frustration over not getting a rack, not getting repairs for 4-way flashers, signal lights and side-view mirror control didn't help.
Long story short, quitting seemed the thing to do.
OK, some venting here; but, What are my options? The pros and cons? What would you do? Thanks.
