How to deal with living apart from your spouse?

My husband is going to be living with his parents for half a year to a year in order to help take care of his mother for a while, I would go with him but well, there’s not really enough room for me there. There’s only a loft in his mother’s room which he will be staying in 😞. To some people that may not be a big deal, but I have a lot of problems with anxiety so it’s just not doable for me, as well as my obligations to my work. Which, by the way, my husband and I have discussed extensively, and we both agreed that we don’t want his parents meddling in our relationship either LOL so living apart seems to be the most ideal option since it’s only temporary.

I’ll be getting my own small apartment for the time being, but i’m going to miss him so much. It hurts to even think about living without him. I have no doubts about our relationship or anything, we’ve been married for four years and we’re very secure in our relationship, but all the same i’m going to miss him so so bad. He will be about two hours away and even though we will be able to visit each other a lot, I just feel like there’s going to be such a hole in my daily life.

I know it’s silly of course, since I’ve lived without him before. But, i’ve also never lived ALONE before. Every time I think about having to live without him, even though a year is a relatively short time (it may even be less than a year) it just feels so so horrible. I know once i’m settled in it probably won’t be that bad but..

in any case, have any of you ever had to live away from your spouse for a while? And if so, how did you keep yourself occupied and from being lonely?

I know it could be worse and all, but again, i’ve never lived alone and my husband is a huge source of security and support for me. I think about it every day and every time it’s so hard not to cry. I know nothing bad will happen, but It’s so scary anyway! Any advice appreciated.

TL;DR no relationship problem, but husband has to take care of his mom for a while and I have to stay back due to work and lack of space, and thinking about living apart makes me anxious as hell and want to cry and i’m worried i’ll die of loneliness and would really love some advice on how to cope with it.
