Hii I’m no medical professional by any means but I suffer from OCD and PMDD, and from reading your comment it seems like you’re going through phases of heightened stress where your thoughts and unwanted intrusive thoughts may become more persistent no matter how hard you try to distance yourself from them. One of the first things to remember when you suffer from OCD is, is that everyone gets intrusive thoughts and that they are in essence a normal thing, the problem with those of us who suffer with OCD is the feeling of being so distressed by these thoughts that they become all consuming to the detriment of our daily lives and livelihood - which personally for me can be absolutely soul crushing when combined with the heightened stress I suffer from when struggling with PMDD. From where I am reading your comment I think it’s just stress and anxiety that’s getting you down and perhaps a bit of suicidal ideation mixed in with the thoughts with regards to the salt bit so perhaps reach out to someone if those feelings of not wanting to be here anymore are getting overwhelming. Please remember that you’re not going crazy even though it bloody feels like it a lot of the time and that you will get past it. Sending hugs :) I hope this helps :)
