Getting used to "away time" for the first time

So my sailor and I haven't been together for very long. It feels like it is still so new because it's hard for us to see each other. Yesterday he went away for training. Communication is pretty much a bare minimum at times. He'll be away for 7 weeks. I am hoping to go visit him for a couple of weekends, which will be amazing. It's really good practice, because I would like to think we will stay together, and if so he'll be on deployment for 6 months next year.
I have had so many emotions though trying to get used to this life. Partly I have felt sad that I won't be able to see him properly for that time. Another thought is that I know the sea is his biggest passion. I would never want to stop him from pursuing a passion of his. The same way as he wouldn't want me to stop pursuing my passion for music. Another feeling is pride that he is in this profession. Another thought is it gives me a chance to sort out the house, and to truly show it off when he gets back. Another side that unfortunately comes out is my anxiety. The anxiety can play horrible tricks with your mind. It makes you think he doesn't care. I just keep reminding myself that if he didn't care, he would have ended it before he went on training. But after all these thoughts running through your head, it leaves you feeling a bit odd.
It's day two, and I am adjusting to not being able to communicate with him. It's similar to when they go out to sea. I'm checking my phone less. I'm getting on with my life. Keeping myself busy. Sorting out the house. I have joined a facebook group, so that way I can talk to people if I need to, and I can see that I am not alone in feeling like this. People who truly understand how I feel. My friends have been brilliant support, but it is a different world.
It has made me realise that the best way to deal with this for me is to keep myself busy. Start a new project. Go see my friends. Plan weekends away. Live my life. Remember why I thought it would work so well in the first place. The chance to have my freedom. But not just whilst he is away, whilst he is home too. I would like to think he'll want to see me when he's back. But he hasn't seen his family or friends either. Or had some time to himself.
My freedom doesn't begin when he is away. My freedom is a permanent fixture.
I also always thought that I was meant for a relationship that wasn't easy. It sounds weird. It sounds immodest, but I think we are picked for these relationships- because we have the strength to deal with it. I just need to look inside myself and see how I have conquered much harder battles. I have coped with horrific grief. I cope with anxiety that can cripple me. I can cope with him being away. I also need to see the plus sides as well. I think that will come after he has been away for a little while and it has settled down.
Until that point, I feel Ms Carey has got it perfectly.
