Have you thought about why you do this? What prompts you to seek help? If you want to cease this behaviour, do you know why? Is it because it doesn’t feel right, as in it’s not “you”, or is it because of the consequences? What worries you, should you live more authentic and truthful, about your social interactions and relationships? Envisioning that folks in most cases react very well if one takes their mendacious mask of, how do you feel about that? Change is hard and those are some questions I just came up with that should prompt you to contemplate in order to understand the root of these behaviours. No need to answer them here.
There’s a lot to unpack there, and I don’t want to appear qualified to help you over this medium. In therapy you could get to the bottom of this, but it takes a lot of work and time. Please have a look into Dialectical behavior therapy, as this seems applicable for the picture you painted about your experience.
