Feeling down.

My boyfriend and I are 18 and we were living with my mom but moved because it's crowded my sister and her three kids stay there along with her husband and my little cousin. His dad offered his home to us but now he is saying we need to leave. So our next move in to his moms who lives with her boyfriend only problem is some times they fight and when they do she decides to move out only to move back in with him a few weeks later so that's not really a stable home either, we are looking for our own place but it's just so damn hard. I feel like crying I'm so sad. I've been going to bible study I went to my second session tonight and that's the only thing making me hold on I'm trying to improve my relationship with God and keep my faith it isn't easy. I'm just so down I'm so worried we won't have a stable place to live once Ava or Baby blue gets here ???
