Is it common for anxiety to spike after ERP sessions?

I read about ERP and have seen information about it on here. One of the goals is to say, "maybe I am this or that...ect." That terrified me. The thoughts and images that go in my head are disturbing and upsetting. I don't want to even think about saying, "maybe this or that." It's devasting to have these thoughts and question why you're having these thoughts. Doesn't the "maybe" make it worse? The one thing that helps me is that is to remind myself that these are just thoughts and I know I'm not a monster, even if I feel like one. Is ERP not for everyone? Has anyone else had a problem with the techniques used in this kind of therapy? I had cognitive therapy for years with an OCD specialist and that seemed to help a lot. Writing out the worst case scenarios would make me suicidal. Im having a difficult time not obsessing over the "maybe" after intrusive thoughts now. It doesn't make it better.

A few hours ago I had my first ERP session and I am currently feeling nauseous and nervous at the same time. Right after my first exposure I wanted to quit right then and there, but I know I cannot. Does anyone have any tips for sitting with this level of discomfort? Anything is appreciated. Thanks! :-)

I had my first serious anxiety related episode back in April and then once in May. My husband had lost his job due to health reasons and spent six weeks looking for work before he finally found something. It was up to me delivering for spark to make the bills. The stress built up and in May I had a panic attack that put me in the hospital. I started Sertraline, had some rough side effects but still noticed a positive change in the anxiety. I still felt crappy every day, but less and less crappy, if that makes sense. (Nausea, heart palpitations, weak, anxious). The month of June was great, no huge panic moments, no racing heart, etc. In one day I went out of town by myself, drove on the interstate, (that’s always scared me), went to the dentist and took my son out to lunch and dined in. It was great. The next day, I argued with my teen all day, it exhausted me and I was dreading spending an hour that evening talking to my therapist. I was just too tired, you know? About twenty minutes before the appointment my anxiety ramped up. Racing heart, trembling, feelings of dread. Normally I can get it under control with breathing techniques but I didn’t have time to before my appointment. Luckily my therapist had overbooked and called me to cancel, so I just rested for the rest of the night, but that’s been six days ago and I’ve struggled ever since. The day after that I was weak and shaky and could feel my heart beat, the day after that I was tired and really beating myself up for what felt like a failure to me, and the last couple days it’s been on and off heart palpitations (my heart rate isn’t going up high, I’m just super aware of my heart beat) and it’s very uncomfortable. My family keeps telling me it’s because I’m stuck in my head and I know that’s true because I spent hours outside in the heat doing garden work yesterday and instead of feeling even worse I felt amazing for the rest of the night and I’ve felt pretty good for most of today. So I know in my head that anxiety recovery isn’t linear and that anxiety hangovers are a real thing and that i just have to be patient for a few days after an attack, but sometimes it’s so hard to think like that when I’m in the middle of feeling so crappy and shaky and weak. Does anyone else feel discouraged like this sometimes? Is what I just described similar to anything anyone else has experienced? If so, what were some coping techniques you used?
