Following the procedure, she had reconstruction surgery with saline expanders and subsequent saline implants, per CNN.Speaking with co-host Jamie-Lynn Sigler, Applegate said: 'The one [text] that I found interesting that someone sent me, and I’ve been thinking this for years, is the breast implant poisoning.'I had my double mastectomy in 2008 and I am way overdue for having them replaced.'And I swear over the last five years or whatever, I’ve thought, "What if they’re leaking and poisoning me?"

Everybody else was so happy.'You don’t get misdiagnosed and then all of a sudden I’m better. I haven’t gotten better, Jamie! If anything, I’ve gotten worse. So I’m back at square one where I don’t know what’s going on with me. 'And that’s going to be an online investigation that my doctors are going to be getting into just to find out what has been going on since 2021, why did this happen?'

'But I lost everything. I lost my job. I lost - I’m sorry. What do you say to someone who’s been living with this for six years - God, I’m so sorry - because it stopped my life. 'I still have to use wheelchairs when I go to the doctor’s office. I can’t walk from the car to the room. I’m still in this. Nothing magical happened when she said, "You don’t have MS." Nothing magical happened.'It’s weird because I feel like I let everybody down, it’s this weird feeling because I became this - you and I, the poster children for MS. 'And everything I was doing. I had a reason. I had a f***ing reason as to why my day sucked every day. 'And now I don’t have a reason and it’s very unnerving and it’s very confusing for me.'Applegate added the misdiagnosis is a 'mindf**k' and that she is still in 'a state of shock' as she seeks answers over the true nature of her illness.

But no, no, no.'I'm sitting here having slept all day yesterday feeling like absolute crap because of the heat. My legs aren't working. You know, all the same stuff is happening to me. And yet I have this thing of like, well, you don't have that, so you know, maybe you're faking it, in my head I'm like, what can I be doing differently? 'What, you know, but this is what I'm sure a lot of people start thinking when they get their misdiagnosis is like, well, what have I done wrong?
