How do I stop imagining worst case scenarios and manage my anxiety so I can do what I have to do?

Instead of thinking in terms of "It will happen" , switch to thinking in terms of "There is a possibility of it" . Furthermore, also think about other possibilities. This should make the anxiety less intense.

For anxiety there are some techniques that can help.For instance one technique is called deep breathing exercise which is one of the most universal things to do while youre stressful.

Thinking about worst scenarios feeds our brain somehow. I used to feel the urge to think so negative and that still happen some times. I can tell you what I do in such cases. First off I distract my mind by watching some really positive videos on youtube. It is important to know why you need to stop. You can never force your mind without explaining it why, so you literally need to make an effort and make yourself understand that why you should not be doing this. This hampers your work, makes your health worse and attracts negative energy. I always think, my body doesn't deserve such a bad treatment. And in the end, if you are not able to manage it all by yourself, seek some professional help, that can work wonders.

try to take walks outside, with a friend or someone you care about. or try to isolate yourself as much as you can.

People who are doing things which they are passionate about always get anxious. Some people learn how to relax in those situations while diagnosed anxious people should be recommended to try out things a couple of times before they are actually done. See on what step you fail. Restart it and do it again. Create list/steps in how to execute a situation. Break down the problem piece by piece so you can have number of shorter goals to execute, which makes the situation very easy to control.

Stop and breathe calmly for a while before reassessing. Think positive. Find your positive path around your obstacles. Strive to follow it.

i really like acting as though i am strong. I talk to my anxiety and say 'come and get me', 'i know you're only n my head' and 'you're not even real'. it may not work for everyone and you sound cray but in times when i am drowning in anxiety i really rely on this technique. Dealing with anxiety as what it is (just an invisible thought trying to trigger some reaction in your brain) can really help to put it into perspective and therefore help you get on with living your life happily. i hope that this helps!

focus on the realistic outcomes of a situation and try to remember all your qualities. you can make it right. breathe, try to be positive and talk about your fears to someone; they will probably help you face them or make you realize they're not so likely to happen or so terrible. think about the result you want, and work for it. fight for the best scenario. once you manage to start, focus on what you're doing, and don't let anything get in your way. if it becomes too overwhelming, relax and take a break if you can, because sometimes it's all you need.

you have to trust what you are doing. and you have to accept that things can never be like what you expected. it doesn't have to be 100%, 70% is ok, and maybe 10%, just learn how to accept it. don't want it to be as you want, don't need the result, don't expect too much, lower your expectations. just do, accept failure, and move on. you are anxious of your failure because because you have failed so many times before, and you also care what people think, you're worrying if people will judge you or act differently if they see your failure.

Sometimes imagining the worst thing possible is a good thing. It prepares you for the worst and allows you to make adjustments. When it causes anxiety there are some things that I do to help. I first ask myself if I am or if my family is in any immediate danger. If not then I stop and take a second to breath. Then I pay really close attention to my thoughts that I’m imagining. Where are these fears coming from? Are they true? Is there a deeper core pattern that is coming up in these scenarios? Then I think about these thoughts as if they happened and how I would feel. An example is “I can’t keep my family safe” then I look at all the ways that I do in fact keep them safe. Which gives my brain the opposite to focus on that is more positive. This takes practice but eventually You will find the opposite of these triggers.
