My First Post-Split Orgasm Was So Intense It Freaked Me Out

I just ended a relationship after three years. We were together since college and it felt like everything was built around us. But last week, we decided to call it quits. The breakup hit me hard, but in the most unexpected way, physically. A few nights ago, I went home alone for the first time. I tried to distract myself with a book, but I couldn't help feeling restless and needy. So, I figured, why not? It's my body, after all. But as soon as I started touching myself, something happened that shook me. The orgasm hit like an avalanche, I was so caught up in the physical sensation, it felt almost foreign to me. My hands were slick with sweat, my legs shaking uncontrollably from the release. As waves of pleasure rolled through me, it seemed louder and more overwhelming than anything I’ve experienced before. It wasn't just the climax; it was an all-encompassing relief that made every cell in my body feel alive. Now, I'm left wondering if this kind of intensity is normal for someone in a post-breakup phase or if there's something wrong with me feeling so... intense about everything. Is this natural? Am I overreacting?
