I have suffered from anxiety for some time now, so I will talk from personal experience!

 First of all, I can't stress this enough: it is 100% normal for you to feel anxious in this time. It is very important for you to aknowledge that for you to be able to deal with that; even if you think you have aknowledged that, it may be the case that your subcouscious is still feeling 'guilty' about it and making you 'anxious because you are anxious', and it is ESSENTIAL to break this cycle!

What has always worked for me in times of greater pressure was concieving achievable goals: sometimes, you can have the tendency to set an extremely exigent goal, and then you'll be anxious when you don't meet it, and it's important not to do this. 

When you can't set a smaller goal (either by responsability or deadlines or something like that), it is VERY helpful to divide your goal into small, more achievable steps! When you have a very big goal, you have the tendency to think you still haven't acomplished anything, when in reality you have acomplished a lot; if you divide your goal into smaller steps, you will actively see them getting achieved and checked off your list, and you will see that you are actually being very productive.

Another very important thing is to know that, if you don't achieve one or more of your goals, the world isn't going to end. Maybe you had a conference coming and you had a breakdown in the midst of all your responsabilities, and you couldn't prepare for the conference: your anxiety will tell you it is the end of the world, that you have failed and that you evaluation will be negative, and whatever else you are afraid of. But this is NOT true! Everyone, anxious or not, fails many of their goals frequently; it is only human to do so! So if you do fail, just tell yourself: "this is normal, this is okay, this is not the end of the world; I have tried my best and, therefore, this is the best possible outcome, so I should not feel guilty about it." Even if 'your best' was giving up on it, it WAS your best because you had so much on your plate, so it is normal to have to leave something behind!

I really am rooting for you in this time of uncertainty. Best of luck with everything!
