How can I stop being nervous when I know I have to talk to someone?

People are generally nervous about talking to someone if they have a negative expectation for how the interaction will go, or they seek to impress them, or both. Therefore, it is first important to identify and challenge the negative expectation, and/or to challenge the need to impress them. This is done by asking yourself questions, like "What am I expecting to happen? Why do I expect this? How likely is this, what is the evidence? Even if it happens, so what?" and also to shift your focus to having a fun, good time rather than seeking to impress. This kind of thinking takes practice, but over time, you'll find yourself less nervous when knowing you have to talk to someone.

You could try to remain calm, think of the person as your friend that you've known for years. That way you will feel comfortable with the person and therefore will feel less nervous about talking to them

Practice talking to yourself in the mirror or talking to a close friend. Kinda like in photography, you take your camera out and just shoot photos just to get your juices flowing, and to get in the mindset. Then when the time comes you have already been active in the task and you feel prepared with minimal anxiety.

Take a moment and breathe is what you have to do first. Maybe repeat "Its Okay" as a mantra. Definitely helps.

You could try and pretend that they're someone else, someone in mind who you are already comfortable talking to generally. Think of a time you was nervous to talk to someone and how they are now an important person you can easily talk to now, this new person could end up going down the same path. At the end of the day, you never know unless you try and not speaking to someone because your nervous could end up in you missing out on something potentially amazing. Dont always take nervousness as a bad thing, remember its also a very good thing aslong as you use it in the correct way.

Breathe. Breathe again. Then breathe again. Then continue breathing. Tell yourself that it is nothing frightful to peak to someone. Think about it from their point of view. If they seem at ease speaking with you, there is no reason to be afraid speaking to them.

Just breathe. It's okay to be nervous when you have to speak to someone and believe it or not, many other people feel the exact same way! Just take deep breaths, and try relax your muscles. It'll be okay.

Take in deep slow breaths, do this until your body relaxes and your nerves subside. Breathing in through the nose for a count of 3 and out through the mouth for a count of 4 can help you relax your body, mind, and nerves.

Know that everyone here has your best interests at heart, and is willing to help in any way they can. There is no judgement.

Take a few deep breaths and plan out what you want to say before you say it. Maybe plan a couple small conversations so that possible responses aren't too much to think about.
