So I had a really bad evening. My little Holmie (our rescue minpin) had a seizure a few hours ago. We rushed him to the vet, and even though he seems ok right now (he is completely his normal self) I am still a mess

The vet told us that sometimes seizures are just normal in some dogs, and as long as they are not happening every few hours then he will be ok. However, we did a blood work up and tomorrow we will find out if it is cancer or a thyroid problem. The first just really sucks but the second is treatable.
Does any one have experience with this? I just am so crazy worried right now googling is not cutting it. Even just a fun picture will make me feel better
