I don’t think we can choose it, I believe it just happens
Good answer Sharon!
Thanks
In my spiritual journey and doing the work to learn what and who I am I have come to the realization that most of our emotions come from outside sources and not all of our thoughts are our own. if you are highly intuitive like myself and empathetic and are a sponge to others’ energy then yes it happens to you sometimes without you even realizing it, however, once you get in tune with yourself you will learn how to decipher if those are yours or someone else’s.
Emotions don’t just happen to us. Different people have different emotional problems. These differences are due to personality of an individual person. This can be genetic make up of the person. Some emotions comes about considering the environment one has been brought up. Some are as result of side effect of a certain drug used.

It’s depends on they version of the emotions.for instant when you are sad,you look for what will clean up ur mood.but when you are very very sad.even that thing that makes you happy can’t fix it…
We can only change week emotions.Our strong emotions are not so easy to hide
