depressed...

Any mamas feeling Depressed and Alone?? I have a 3 year old who is wild as all get out.. And I husband thats works all the time. I love my unborn baby so much but I'm already so stressed with one child. And I feel so guilty for thinking like this. I hate being alone because thats when I think about how hard its going to be. I already feel so alone and feel as if I dont have any help now. I'm all in my feeling and just want to feel happy and normal but my mine want let me. My husband is a wonderful man but he just doesnt understand my depression so therefore I feel like I cant talk to him about it. Its not just having another child. It being alone all the time and feeling as if I have no one there. My mind is just everywhere. I feel so bad and just guilty for even feeling like this.. We tried for over a year to get pregnant and I'm beyond happy and love my little one so much. I'm just scared that I want be able to do it alone and stay sane.

I know this post is kinda all over the place but I have no where else to turn to, I just want to bw happy abd feel ok.
