Depression effecting relationship

Idk if I want to call it depression. But I have been through a lot of aweful shit. Physically and emotionally abused by boyfriends, been in physical fights... Just a lot of shit I didn't deserve and it has effected my personality. I don't laugh like I use to. I am just like empty inside even though I got a new amazing boyfriend. He really tries to make me happy but says it's a challenge. I don't want him to feel like that. How do I just be happy and have a good time with him and make him feel appreciated and loved?
