Stress Clouds my vision... life/relationship Advice?

Okay, so here’s the deal, I need to write it out.
I am a rollercoaster of emotions lately, some days happy, some days so stressed and tense that I take it out on everyone around me.

I am on this rollercoaster due to the uncontrolled changes happening in my life concurrently.

I was transferred to Los Angeles for a temporary job a little over a year ago. The job was supposed to be over in August, but contract extensions have it still chugging along. However, it is unlikely it will continue past December. So, I am facing losing my job in the next few weeks. If I am willing to relocate again then my company might have another temporary position for me in Washington DC, New York, or Seattle. I have transferred with them a few times so far (Seattle – Santa Barbara – Everett – Los Angeles).

I have told them this time I am not willing to relocate. The reasons being that I have been dating a guy here in LA for this year; I could love him, and I have a friend from High School/College years that lives here as well; who I have been enjoying reconnecting with. My family (Mom, Dad, 2 brothers) also live within a few hour radius of LA, so being able to connect with them often has been a huge bonus.

Here’s where I get my stress:

I don’t know if I see a future with the boyfriend. …and I just moved in with him because my Lease was up and he offered…saying it could be temporary or long term, just for now it’s a place to stay until the dust settles on the job ending. Very nice of him of course, but it has me stressed because I don’t think we are ready for living together…AND It is only 1.5 years ago that I left the man I had been with for 7 years. So, living with someone new seems a bit suffocating so soon. However, it is allowing me to save up a little while waiting for my layoff…(my belongings are residing in my parents garage)

I am torn also over work…I could tell them I’m open for relocation, and thus keep open the possibility of them finding me work, it would obviously mean a move though…which would definitely squash the relationship. I wonder if my hesitancy to relocate is because I hold out hope of making it work with the boyfriend, and then think, is it worth throwing away your job? But again, there are other bonuses to being here, as I mentioned before. Am I creating animosity within the relationship over this link; thinking it should be going better if I am ‘staying for him’? Am I placing extra value on being close to family, friends, etc… in order to justify staying so I don’t have to walk away?

I have been thinking that LA offers a lot of career change options that appeal to me, if I could find a way to break in. I work as a Construction Field Coordinator, and would love to translate that skill into being a coordinator for Studio Shoots…Example – Coordinating all the trailers, meals, etc on film shoots. There’s a million options in LA for that kind of work (if they would consider me with my related, but not actual experience). I’ve also always thought of working as a Make-up Artist. I used to do make-up for free on little indie movie shoots in the Seattle Area in my early 20’s, but I have no professional training, and I know it would mean a massive pay reduction.

I don’t know what tomorrow holds, and the lack of control is tearing me apart.

Any advice, even a 'Just Breathe' would help and a friendly reminder to not eat/drink my stress, and undo my hard work.
