For one thing, I'm a hairdresser as well and feel like I can't decide on my hair/clothes. You could be going through the 'baby blues' which is very common. Post partum depression is a little more serious but also common and you should discuss this with your Dr to make sure everything is alright and he/she can give you ideas or meds to help.
Daily excersize, a structured day, getting dressed and going out, having a date night once a week... all can help. Try a baby and mom yoga class, join an infant mom's group. Also, doing something for yourself is great. You can't take care of a baby if you aren't at full capacity.
