Firstly. None of us are where we thought we would be..but you are on a path so this is good..scary yes but exciting..
Please dont define yourself to grades achievement is so much more...
The fact that you know where you want to be is a positive, some of us are on a path unsure of where it will go, often with lots of suprise twists but all you can do it manage one thing at a time..we are not here to make others see our worth...you are already worthy and its only yourself you need to ensure who knows it...once you have done this the rest will fall into line..
