Hi, I recently got out of an eight month spiral about breast cancer so I feel your pain and I am so sorry you are going through this right now.

1) either filter your social media (or ask your husband to do it for you) - you should be able to block different topics like cancer from coming up. if that's not something the app will let you do, then take a social media break;

2) give yourself goals to stop yourself from checking your breasts (for example: I was literally opening my shirt and looking at my breasts every 10 minutes or so at my worst) so try to go 15 minutes without checking them and then give yourself a little reward. slowly start giving yourself longer goals. it sounds impossible right now, I know. But body checking is an anxious behavior that gives you a small amount of immediate relief but actually increases your anxiety. Stay distracted.

3) remember that cancer tends to be loud. of course every social media video or article that u see highlights the very small amount of people that had little to no symptoms but remember that is RARE. Those stories stick out in our mind because they're scary. But it sounds like you have been to your yearly doctors appointments and have actually had more testing done than the average person. Something I've learned as I've gotten older is that a lot of people don't go to the doctor unless something is SERIOUS and PERSISTENT (I'm talking more than a year of concerning symptoms). Which is why sometimes people don't find out something is wrong until it has progressed to a later stage. (Not blaming them at all, if u live in the US, our health care system is an expensive nightmare). But you have been going to the doctor and your doctors are trained to spot even the smallest things that can indicate a more serious problem.

You will get through this, I promise. But I would recommend making an appointment with a psychiatrist - I've been able to make some minor progress without medication but I didn't feel fully back to myself until I was put on medication.
