Stop.........
1.) You fear that he/she will leave you?
2.) You fear that he/she will cheat on you?
3.) You fear that you will be alone for the rest of your life?
4.) You fear that the person you like will not like you in return?
5.) You fear that you will be alone so you stay in a dysfunctional relationship?
6.) You fear that you will never marry?
If you keep fearing/worrying about all these things they will happen because you are manifesting the negative.
The best way to handle this is to manifest positive for example, I will marry one day.
Ok, these may sound very simple but they are not. The mind has a lot of power. The thoughts you think can easily work for you or against you.
