That happens to me a lot. You've taken the first step already, telling somebody about it and asking for support. You need to focus on your senses, on the here-and-now. Do something to pamper yourself, as if you
were a child who came to you crying from a nightmare. We all need comforting sometimes, and doing these things will help change your mood. It happens to me all the time. Distracting yourself from it
and reminding yourself that you're safe, and none of that is really happening, and people care about you, can help. If there is something easy you can do to feel like you've accomplished something, do that.
I'm so sorry you had that happen. I know exactly how it feels.
Take long, slow breaths. In through the nose, hold it about 3 seconds, then out through the mouth. It will energize you and clear away some of the short-term memory hangover from the dream.
Put on music that makes you feel good, especially energizing music. If you have a favorite perfume or a scented candle, smell that. Feel a soft blanket or sweater on your skin or take a bubble bath. You want to
involve all your senses if you can because it tells your poor, dumb body that everything is okay, and if your body believes it, it will drag your mind along with it.
If you have a hard candy or a fragrant tea that you like, having something simple that tastes good in your mouth also signals your brain that everything is fine.
lots of fur baby cuddles

I sure hope you feel better and I love all the suggestions for helping.
That happened to me a few times.
If something helps you, note it in a journal or on your computer desktop or whatever reminder program you have so you can remember it for later. It's key to getting control of this stuff and being able to
work with whatever stuff is coming up for you. Also, if you remember anything about the dreams, write them down, too, because sometimes you will gain insight when you start to see common patterns.
Only if you can, though. Sometimes you can be too shook-up to get to it. Nothing to feel bad about; number one on the list is emotional first aid.
Not crying. I have woke up pissed off and couldn't shake it...
I did this the other night when Jake was out of town. I told him its a lot easier to wake up severely pissed at him when he's in the bed next to me than not.
