Pray the rosary and fast for a minimum of three days. Both do wonders to kill vices and to subdue your body's lower passions. Much like how an army surrounds and cuts off food and water to a city/settlement to starve the populace until they submit, you must also do the same to your body to make it submit to your mind and God. Praying the rosary will also help as it is our weapon agianst vice and keeps your mind centered around God. Prayer also helps dull the hunger pains.
Also, throw away any clothes you use to crossdress and delete any numbers and apps related to your sin. Heck, if you want to play it safe. Just get a new phone number and only tell essential people the new number (work, family, friends that don't enable you, etc).
And of course, I will also be praying for you. Remember, you have a family in heaven rooting for you and cheering you on as you fight this spiritual warfare we all must endure. God love you, OP.
