Marriage counseling

My husband and I are about to start going to marriage counseling. I’ve heard horror stories of marriage counseling making things worse. Is this true for anyone? Weve realized we’ve changed quite a bit since he left for deployment. He left when our daughter was 6 months and got back when she was 13months. So my priorities changed when it was me on my own and his changed on this last deployment. He got home in October and we haven’t been fighting but we’re not as “in sync” as we usually are. We disagree and pick so it’s not like usual so we are going to a counselor. Any advice?
