How can I stop trembling when I'm anxious?

Your body and mind are connected. If you are trembling due to anxiety, the best thing you can do is target your anxiety. Why are you feeling anxious? What is making you feel anxious? Reducing the anxiety will help alleviate that mind-body connection and allow your hands to be still.

Anxiety reducing techniques can help. Grounding Techniques, breathing exercises, mindfulness, positive self-talk, positive affirmations, and challenging distorted thoughts can all help deal with anxiety and thus lessen shaking or trembling.

breathe in and breathe out and ask for help. its never bad to ask for help, especially if you need it

The most important thing you have to remember is to breathe. A lot of times it's hard and seems impossible, but once you escape into that place in your head, your safe space, it makes everything so much better. Your safe space could be songs that hold meaning to you, it could be memories of times you were truly happy, but whatever it is, it helps calm you down and help you to just breathe.

Deep breath, mental projection in a calm place, focus on your attention on your breathing and muscles: try to reach with your mind every contracted muscle in your body and try to relax, starting with your toes until you reach your facial muscles. It's preferable to be lying down for this exercise, or sitting, in order to let your weight be carried by something external to you.

Maybe using a squeeze ball may help you to calm you down, and try breathing techniques along with telling yourself that it's going to be ok.

I've been through this too! What works for me is to talk to myself and remind me that this is happening in this moment. Then, if this works, I try to concentrate on breathing properly. Sometimes, its been so intense, I feel like I can't breathe plus the trembling. Thankfully, I've found the strength just to call my support place and they help too. One of the practices I adopted recently is as much as I can, tell my me that this is the present moment, this will pass and help me stronger to get through the next episode. I feel like if I stay in the present moment, I could almost feel when an anxious episode is coming on. Still a work in progress, hope this helps and thanks for asking.
