Advice please.

So, I don't know what to do.

My husband and I have been together for four years married for one in December. Everything was fine we HAD our own house until he wanted to remodel one of our own, which I didn't mind until he told me we were selling the one we were currently living in. Now for the past year we've been newly weds. Lived with his parents for six months and now living with his grandmother which has been complete hell. She tells him all the time that I leave and don't come back on my days off, to which I now do overtime to get away from her. She will scream and throw a tantrum when she doesn't "get" her way. She constantly badgers my husband to do something even when he's late for work. She never moves from her recliner to do anything. My husband and I have recently been TTC after an unexpected chemical pregnancy, it's been wonderful to try with him. But with her it's miserable. When my husband tells me his recent depression is because of her, and me because we don't get along even though I have tried to with her. I'm not going to take getting screamed at and belittled by someone. I just don't know what to do.... We have still almost 6 months to a year on our house before we can even think about moving in. It's so hard on me, I have major depression and anxiety due to my past. Does any one have any advice for me to help me and my husband? I've recently contacted my doctor to get counseling to have someone else to actually talk to and help me out but there's a very very long waiting list.
