Anyone else have a wonderful day and then suddenly at the end your mind spirals and you feel sad. Then you worry that you ruined the day for everyone else...

Does anyone else ever feel like this? When you're having a good day without a lot of fear after having multiple days of fear, you start worrying that your good day will be ruined by fear again. It's like anticipatory fear. Anyone else get this? I hate it but I don't know how to make it stop

just when I think i’m having a good weekend and I can forget about my struggles my brain tells me i’m not allowed to feel happy and that there’s always SOMETHING i need to be worrying about. so frustrating :(

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
