Sounds like you are doing well - I know that is doesn't sound like it or feel like it - but everything is relevant - you are still able to eat - and though tired - able to do yoga etc... So these are all pluses. Women in particular are notorious for pushing themselves to do more, feel better, etc.. You Are doing what you have to - you are almost at the end, that's fantastic. Best of luck to you and many blessings - it hasn't been easy for you but in time - hopefully it all will fade.
