Nightmares

It's night time again and as usual I'm getting anxious about going to bed. I'm not sure what the trigger has been but my nightmares recently have been really loud and really vivid.
I had hoped that the prazosin was going to help more with my nightmares and stop them being so bad. I'm seeing my psychiatrist next week and I'm going to see if I can up the dose to see if that has any positive impact
I'm definately not having as many wet beds and that is helping but the content of my nightmares still has such a lasting impact on me. My CPTSD goes into overdrive and stays with me during the day. Simple smells and everyday sounds trigger images and negative thought patterns and they are hard to shift.
It's getting me down and I'm trying hard not to let anyone notice but I wonder if I'm heading for a fall. There are times during the day when I can't breathe and I just feel panic. Holding my head up and soldiering on is what I do but I'm not sure it helps. Maybe I should be more open to let people help me but I hate it when I'm let down or I feel judged
Someone told me to write down my nightmare in as much detail as I can but I'm confused as to how that will help.
I hate my nightmares and I hate nights.
