Job hopping to just plain, jumping ship.

Don't know how many people actually still read this, but I've been through some dark times over the last couple of months.
From a lengthy time at a rather nice place of employment in a industry I've been troubled with, to just wanting to get away from it.
The pressures of commercial vehicle driving aren't for everyone and the fact that I've entered and exited with the frequency of a person who doesn't know when to quit until it's too late is one sign in many that I should just stay away for good.
By staying away for good, I should do two things;

1)Get back into a previous job that didn't leave me with the clenching feel of anxiety everyday.
I've been employed in the security field for longer than I've driven trucks.
I go to work, make sure all tasks required of the post I'm assigned are completed, then go home(could be anywhere, really) and do what I please with my downtime. No sweating work until I'm actually there again.

2)While working a regular job where it's easy to keep it separated from personal life, I should refocus on a field of study in college that I found interesting and worth doing.
Vocational-tech fields like welding and vehicle maintenance were courses of study that kept me coming back and yearning for more.
In addition to the classes not really feeling like classes, the types of people attending were from varied walks of life and this enjoyable, yet productive common goal actually made me more sociable to the point of knowing physical people in real time.

Looking back on positive experiences like this and racking them up against the multitudes of negativity I've experienced every time I've been on the road makes me wonder.
If not driving trucks gave me more positive and productive experiences than driving trucks, then why did I complain about not doing it for so long?

The answer to this lies in the fact that I was having a bad home life and just needed to find a different place to lay my head at the end of the day.
The only thing trucking has afforded me in the productivity department thus far is discovering and finding a liking for places I thought about moving to.
Since I've found those certain places, I feel it's time to get on with things I want to do and to stop suffering from these daily bouts of anxiety pangs I get every time I attempt to get myself out onto that 2-8 lane stretch of Hell known as The Freeway.

It's up to me to see to it that this latest company I've jumped to will be the last and that I could finally say goodbye to it within the next 5-6 months.
