Need advice

I'm convinced I've been having severe anxiety attacks lately and a bit of depression. My SO job took us away from family and I was/still am very close to my sisters and nieces/nephews. We have been trying for a transfer back home but haven't gotten one yet. He works nights and sleeps during the day so I am basically a single mom. I'm alone all the time and can't leave the house really because it's such a hassle. Long story short, I've been thinking about going back home for awhile just to get some help and peace of mind, but I'm not sure if I am being selfish or not. I don't want my SO (we aren't married) feeling like I don't want to be with him, but he can't help me the way I need. He has been supportive and wonderful but he doesn't really understand how sad and depressed I am... Please give me your honest opinions
