Hi lostinlife.
Sounds more to me like you moved away from where you were so happy amongst friends, family maybe, a job you liked and you slowly ever so slowly have lost all of that, as friends can only email/text for so long before continuing themselves with their own life.. in the "real world" more so and they do.
Now you have a job you don't like and no friends and it has gotten you down to the point you don't know who you are.
Well, your the same person and you may just simply be depressed that would be my judgement if i was to make one and off course we don't judge here... so opinion will do.
Panic attacks are caused by the un-known, fear..
But you should discuss with your doctor that you feel depressed as well if that be the case, because it sure is sounding that way.
You have a boyfriend that you love , one for you.
You have a new puppy that you love, two for you.
Now you need to make friends, they won't come to you, so work out what you love doing, hobbies, etc, and start mingling in those circles and get to know people that like things you do.
Once, you start to make friends, you will be happier and more yourself again, your relationship will go back on track and you will want to work and seek a job you like, you will more than likely re-gain communication more with those friends as well but on a happier note, light... If you are communicating with them that you are down, they will understand but everyone likes happy people, including yourself, you know her, she's not lost, she's just in transition...
