If you are looking for stress and anxiety management, then you should know that there is no one right answer. This is because each person is different so finding the right way to manage it will be different. Overall though there are a few things you can do.
Exercise- Even though it seems like this is the last thing you want to do or have time to do, it is important for your body, even if it just means taking a nice walk.
Find Time to Things You Love- Sometimes it is just a matter of getting in some time for yourself. This can look different for each person.
Meditating- This does not have to be a full meditation, like what you see on TV or in movies. Rather, just find a way to focus your mind on something. Some people find it helpful to focus on their breathing in a room where there are no distractions.
Seek Help-Whether it is a professional therapist or just a listening and helpful friend, finding someone to talk to is very beneficial. It can help you understand what is causing your anxiety and stress and can help you find ways to alleviate it.
