I don't know where else to go

Last night I wanted to hurt myself. . I've been dealing with my anxiety and depression for sometime but lately it feels like I can't go a day without breaking. I'm currently in a serious relationship and I know my boyfriend says he's happy but I see it in his face that he wishes I could be "better." He's the man of my dreams and I don't want to lose him but I feel like I'm losing myself. I want to be a stronger person but I don't know where to begin. If anyone, absolutely anyone, has any advice please let me know. I don't want to keep living like this. I don't want to hurt myself again. I don't want to have anxiety attacks. I don't want to feel useless and hopeless. . .
