<human>: Can you provide a brief rundown of the text in within 3 sentences?

Me: f(21) Him: m(29), been together about 1 and a half years before getting married. 
I need some advice on this situation. I just moved countries to marry a man in the US (I'm from Australia). I love him more than anything, but being with him has meant having to leave all my friends and family, leaving university and my part-time job.
So now I'm here. We just got married. I am so happy to get to sleep in the same bed as him every night and wake up to him every morning (being in a long distance relationship for a year has made me value his presence more than anything). The problem is that I can't work just yet due to visa restrictions. He has a good job so is able to support me, which I am SO GRATEFUL for! He really is amazing, but yet I'm unhappy.
I'm incredibly lonely here. I just feel really down all the time and I can't seem to shake it. We'll be sitting watching tv or something and all of a sudden I'll picture my dog and think about how I miss him so much and have to hold myself back from crying. I feel so guilty about this because I don't want him to think that I'm not thankful for him working so hard so that I can live with him. I mean, I'm living the good life, I don't have to work, I should be enjoying having all this free time and that right?
My question is, what should I do about this? He asks me all the time if I'm okay, whether I'm happy with him, and I want to tell him how I feel, I want to tell him that I miss home and I cry a lot, but I'm afraid of the repercussions of doing this. 
Any suggestions?
<bot>: Just moved countries to be with my husband, now I miss home and I'm sad all the time. How do I broach the subject without coming across as unappreciative of the work he does to keep me here.
