I wont baby you. All i did was tell you what you already know and what your doctor SHOULDVE explained to you before the surgery. You are three weeks out, on here commenting that your life is over and everything is ruined....after THREE WEEKS.
What you should be doing is focusing on your program:
Drink water
Eat popsicles or Jello
Get lots of rest
find something to engage your mind - and keep you from dwelling on these depressive thoughts you described here
start working on Protein intake to meet that goal
You can worry about your friends and your old life and doing all the things from a social aspect later.
This isnt a Jerky comment....this is providing you an ANSWER to help your original question, but you dont want to hear it so you take offense.
