Worrying about something does not change the outcome of it. Worrying will only deplete your energy and take away your Joy. Worry produces anxiety, depression, and loneliness. If you can fix the problem, then fix it. If you can't, allow the Universe to handle it. Have faith. Lift your hopes up. Strengthen your spirit. Believe that everything is working out for you even if it does not feel that way. But if you constantly believe then your faith will bring to you this reality.
If you are surrounded by people who constantly worry and bring fears and anxiety into your life, avoid them or change your circle or if you cannot, just choose to feel differently. Refuse to vibrate in a low frequency like them. Set yourself free. Focus your energy on things and people who can bring you Joy instead and to thoughts that can make you a better version of yourself. Remember, you attract who you are becoming. Therefore, if you are always becoming worried and scared, scary things and situations will show up more into your life to prove to you that you are right.
Hope strengthens your spirit.
