Hi Elly and welcome,
i had my bypass on 2.12.11 and lost just 5lb in the 1st week so you are doing fantastic. as for being emotional i was great the first few days but this weekend has been a bit of a battle all round and i have found myself in floods of tears for nothing. what we are going through is a massive lifechanging experience, if we compare it to other such experiences, getting married, giving birth, moving away from our parents for example these are all lifechanging experiences that turn out emotions upside down. It is just a period of adjustment and with the right people around us for support we will get through this. Big hugs xx
