I don't want to sink beneath the ocean I finally could keep my head above but the one in my mind is using a weight drag me down beneath the ocean but I don't want to sink

I don't want to sink but my anxiety is using a nightmare as a weight this is different and I don't know how to deal with it she used a nightmare to make someone in my life physical form fear for me and I don't know how to change that because I've never had to deal with this before this is different she's use my dreams against me before but not like this and because of this nightmare it's hard for me to see this person to be near this person to hear their voice because this is someone I work with I have to encounter them every single day of my life and I barely know them so when my anxiety tells me things like what they're thinking I don't know isn't true because I don't really know them she's making me over analyze every single thing this person says to me I don't know how to change that I don't know how to forget the nightmare when there's so many emotions she's tied to it I don't know how to unbind this weight but I don't want to sink
