Anchoring.
Sometimes, we just need to feel rooted so that we can be safe. Think of it as anchoring a tent by securely fastening guy ropes and banging tent pegs into the ground or casting an anchor from a boat to hold it steady in the winds and water.
 
You can ground yourself (as in Tip 8) and have a sentence or phrase ready to repeat to yourself to anchor you in the here and now. You can adapt any sentence which makes you feel secure. For example, ‘It’s (insert time) on (insert day) and I am (insert location). I am safe. Holding something like a stone or a small favourite ornament or picture can really help to anchor you too.

Grounding.
Making sure we are firmly in our physical bodies rather than lost in thoughts in our heads can help us to feel safe and secure.
 
Sit down and place your feet flat on the floor. Notice how the floor supports your feet and the chair supports your seat bones and back. Try to feel yourself solidly into your body. Keep your eyes open as it is easier to stay connected to what is solidly around you. You can pair this up with anchoring and noticing (see tips 9 and 10).

'All that we are is a result of what we have thought. The mind is everything. What we think, we become.'
