If you are dealing with something like anxiety or depression in a way that it has a significant impact on what you do (or avoid doing) in life, then psychotherapy might be a way to change this.
Other issues like
sudden outbursts of sadness or anger
the need to keep a certain structure in life
finding it hard to concentrate or
feeling tired all the time
are also topics clients often bring to therapy to improve their experience in life.
Some simple strategies taken from well researched therapy modalities can make a big difference. To look into the body-mind connection is a very important aspect of this. We all know this, but often ignore the possibilities that, for example, a change in breathing can change the state of mind. Who has not experienced anxious moments when the heart rate and the breathing changes. It works the other way around too, which is fabulous and gives us a bit more control over our mind. Combine some of this with an exploration of life events that impacted on us and we have a good recipe for positive change.
