Anyone else feel this way with second pregnancy?

I'm almost 7 weeks pregnant with mine and my husbands second child. It was a planned pregnancy, we tried for 3 months before we conceived. All I thought about before I got pregnant was how excited I would be when I got pregnant again and how exciting it would be to plan everything and to be expecting another baby.. But since we've found out over 2 weeks ago, I just feel no excitement at all most of the time. Sometimes I'll get a little excited.. I wanna know why I feel like this and Is this normal? I feel like it's not. I just wanna know if other people have went through this and if it got better with time. I feel so bad for not being excited and I do try to be but I can't force myself... :( I feel so depressed at times and scared that I will feel this way the whole pregnancy. My hormones are out of control most days and I just feel so not myself since getting pregnant. I just want to cry Becuase I want so bad to know this will get better. Has anyone else went through this? Please no negative comments, I already feel bad as it is. :(
