It is ok to feel stressed from time to time, but once you don’t have a regeneration phase afterwards it really gets tricky.
Your body needs rest after a particularly stressful time, e.g. to break down harmful hormones. This also applies, if you have had positive stress! What kind of recovery works for you, you have to find out individually. Here, too, everyone reacts differently.
Often you get a lot of advice here, which can fit you, but do not have to. During my burn-out time I was often recommended things like meditation or autogenic training. These are ways to reduce stress, especially meditation is something I use a lot today. In the “acute” phase, however, this made everything even worse for me. I had to exhaust myself.
In general, you can distinguish 3 different types of stress reduction. There are people who get rid of stress better when they exercise or a massage helps them. For others it can help to go to a museum or to visit an art exhibition. The 3rd type need to listen to an interesting audio book or simply go to a concert. Of course there is no clear separation here and for you a mixture of these might fit best. The only important thing is that you find your way to reduce stress.
