He said he thinks he has lost me

My boyfriend and I have been together for 6 years in the beginning it was lovely I felt like I was me again.( I was in a bad relationship before and let him take control of my life and my friendships and my world was him then he left) I was depressed and then meet the wonderful man I'm with now. He would probley do just about everything for me. He wants me to go places with him family gatherings and stuff. The past three years we have had money issues so I try to stay home as much as possible. He told me last night he thinks he has lost me to depression. I feel terrible we have 2 kids. I love them all so much and can't go anywhere. I have cut myself off from everyone else. I have a aunt that is like my big sister I don't feel like I can express myself to her anymore she has told him recently that she thinks I don't want her around. He told me if he was the only one I could talk to that was fine but he don't understand that I feel helpless. I am strong most days I have happy moments but I don't want everyone to judge me I havent seen most our family in over 4 months. How could I possibly be able to be there with him with out feeling like it would be better if I wasnt there?
