It is possible that in your relationship you have begun to feel anxiety. The reasons can be many and varied, but we will not go into this now. What we want to do is help you so that if you have anxiety in your relationship with your partner (or with the relationship of any loved one), learn what to do to get back to being good with yourself and with the world around you.
Relax
All those "what if" questions can't change anything, now or in the later stages of the relationship. Put aside your need to control the outcome of the situation and just relax and live in the moment, so you can really enjoy yourself.
You may need to reassess your expectations
If you've already worked out your entire relationship life plan in the middle of your first date, your feelings of anxiety will increase with each passing day if what is happening doesn't match the timeline in your head. Is it worth going through anxiety about things that you don't even know can happen?
Exercise
This seems very simple, but be physically active with sports, the gym, etc. Exercise is great for reducing anxiety levels and helping you cope with anxiety symptoms while working to eliminate them mentally and emotionally.
Do not neglect yourself or your life
Just because you are in a new relationship does not mean that you should focus all your time, energy and dedication to one person. You will suffocate your partner and start to feel bad when he or she does not react with the same level of vigor.
Recognize that everything is not always about you
If your partner displays unusual behavior such as withdrawal, for example, does not mean that I am losing interest, dating someone else, cheating on you or something like that. There could be many other reasons why they seem to be withdrawing (family, work, or health problems). Have an honest, calm, and rational conversation with your partner about things.
Listen to your feelings
If you start to have any of the familiar feelings of anxiety, take a deep breath and step back: write, paint, hit the gym, or go for a walk. You may not be able to control feelings, but you can control your reaction to feelings.
Be the driver of your life and your reactions. Don't do crazy things like running after your partner, posting passive aggressive updates on social media, blasting their phone with messages, or sending a 10-page laden cryptic email that only you can crack. Use your enhanced awareness and awareness of the possible reasons why you feel anxiety in a new relationship in your favor.
Be patient and learn to manage your feelings. They will help you build a stronger and longer lasting relationship. And if this doesn't work, that's fine. This is life. You will feel better and with more self-power to enjoy the next relationship… You can be happy without anxiety!
