How do you deal with the anxiety of being in the closet?

i understand where your coming from i to am in the closet and it becomes such a burden you have to hide your partners lie about who your seeing i moved to another state so its easier now to go on a normal life i know people that have had it hidden until the day they died its not a easy rode you have to decide if or when your ready if you don't like your parents then why do you care what they think just tell them that your gay your going to lose support but do you really need it
