Often in our lives, we come across a time where we start questioning our worth based on a failed relationship or an academic setback, or any hitch that comes in the way of our perfect plan. It's good to question things now and then but it's not supposed to hurt your self-esteem. The reiterated questioning linked to your worth leads to an unhinged core belief which is self exploitive.
To overcome such beliefs or thought patterns one needs professional help from the psychologist. To aid the therapy process experts have extracted 3 life-saving techniques from literature to overcome negative core beliefs.
To strengthen our negative core beliefs we indulge in a "filter thinking pattern" where we filter all good thoughts and keep the bad ones with us. It is when we focus only on negative things and to overcome this whirlpool of negativity we need to remind ourselves of our accomplishments whether small or big, just list them and give yourself credit for it.
It is vital to remind yourself of all the habits and attributes you have which makes you, YOU. Whilst experiencing negative thinking pattern, remind yourself of your generosity towards strangers and your loyalty towards your friends. Remind yourself of the time, you didn't derail from the path when everyone thought you might.
Ask yourself that what if a friend was in a similar pit of negativity, how would you have reacted. By doing so, you will realize that you were "catastrophizing." You are making your situation way worse than it is.
These techniques work if used while consulting a mental health expert.
