Your “default” emotional climate is just an acquired habit. You can change it anytime you feel it doesn’t serve your highest good.
It is just a mechanical habit you have adopted to help you cope with the world. It feels frightening to change it because that will mean people will react differently to you and you may miss what you have been getting from them. It is a coping mechanism.
It’s just like your first sex style was a missionary. You learnt about the others later but it took you time to try them with your partner. What would she/he think you going for doggy on the second day of the honeymoon?
It takes deliberate effort to reeducate your emotions. It is difficult at first, but it gets easier with practice. It is the same process with all habits. You learn the desired state as you simultaneously unlearn the undesired state.
