should I kill myself because I cant get hired by anyone in san diego cause im 33, have 4+ industries experience, 2 certifications or give up?

I disagree with sinead you should weigh up all your options and never dismiss one for no reason. Maybe write out a pros and cons list

You should see what do you
1. Like to do. Take a free personality test to find out https://goo.gl/7t4LZw
2. Can Do. A Skill Test https://www.careerinfonet.org/skills/default.aspx?nodeid=20
Results of these two combined would give you a good idea

San Diego has unemployment of 4.1% which is one of the lowest unemployment markers ever.
Don't kill yourself over a stupid job.
But you really do need to change your job search strategy, since your currently process is not working.

If you can't get hired by other people's companies, create your own job... there's bloody loads of books telling you how to do so in Amazon's kindle store.

Selling stuff on Ebay is one popular route

Creating a YouTube channel and making money through ads + marketing stuff through it is another popular route now http://www.jdaltpol.co.uk/youtube-income.html (playlist at the bottom worth a watch)

Blogging is also becoming a popular escape route for people struggling to get a normal job

Failing that, San Diego isn't the only city in the United States... and California ain't even in the Top-10 places in the US to find a job, with more viable options such as Utah, Nevada, Colorado, Texas + Tennessee

There are many reasons to kill yourself.
That isn't one of them

Killing oneself is never the answer
