Suicide over a job

I feel screwed at 50 by corporations....here I am 50 years old, loads of experience, energetic and young looking I might add...can't find a job...my jobs are being given to 25 year olds with 1/4 the experience.  My recent experience is with CPI or better known as picture me portrait studio..read previous blogs.  What do we do about this?  I am left feeling worthless, depressed and seeing no point in going on I do not see anything changing at all!!!  Thank you to the District Manager a women I might add Pam Copeland for judging me not on my ability but my age.
