I am not in any way any sort of medical expert. These are just some tricks that work for me and have worked for others who also suffer from anxiety. These may not work for everyone, but I do hope these help some people in their fight against anxiety.
1. When you start to get anxious, rub your middle finger and thumb together
This is a trick that works super well for me. This distracts your mind and allows you to focus on something other than the anxiety and the panicking feeling. Distracting your mind is a way to keep yourself calm. If a person starts to feel anxious and they just focus on what they are feeling, it can make the anxiety worse.
2. Realize your triggers
Try to find out what sets off your anxiety and what causes you to become anxious or out of control. Once these triggers are learned, they can be avoided or prepared for. Usually, anxiety comes at times when a person feels out of control. A person can prepare when they know their triggers and if they can't get their anxiety to fully go away, this may help at least to limit it.
3. Count to 10, forward and backward
Just like the first trick I mentioned, this helps keep your mind distracted and allows a person to focus on something other than their anxiety. Like I said before, distracting a person's mind when anxiety sets in is critical. This can help overcome or at least lessen the anxious feeling.
4. Smell lavender oils
Lavender is an essential oil and has many properties that do many different things. Smelling lavender oil or using a lavender soap/body wash can help relax a person's body and mind, allowing them to fall asleep and get a more restful night. Lavender is also seen as a natural stress and anxiety reliever.
5. Remember to breathe
Often when someone starts to panic they feel like they can't breathe, and that makes them panic even more. Remembering to breathe is definitely one of the main things to remember when starting to panic or feel anxious. Focus on breathing and feeling the air filling your body, it can help keep you calm. Take ten deep breathes and take a minute to yourself and then restart.
I hope that these tips help at least one person handle their anxiety a bit better and make them feel more in control.
