Loose skin, hair falling out

I have just had a lovely baby girl only 7 and a half ibs and my pregnancy was straight forward, no complications and i wasn't even that big, but after 3 months I am still left paranoid about the loose skin that i am left with - It is horrible - My stomach is all loose and droopy, I can't even be intimate with my husband properly because i can feel it and i know its there. Also because of all the stress i am beginning to loose my hair - both of those together will leave me a mess!
