Withdrawal Trouble

Today is day 18 of my NoFap journey on Hard mode. Before I quit PMO I was diagnosed with generalized anxiety disorder and depersonalization/derealization.Since I have cut out all forms of porn and masturbation. I struggled with PMO addiction for about 7 years. My situation seems to get worse from day to day. I don’t watch porn but I find looking at Facebook or Instagram to be quite triggering and my Withdrawal symptoms are the following:
-Worsening Depersonalization and brain fog
-Headaches at night
-Inability to concentrate
-Severe Panic attacks
-Anxiety
-knee pain and body aches
-dizziness
-insomnia
-insatiable thirst
-odd feeling in urethra after/before urinating.
-being a hyperchondriac
-impotence

Can anyone offer some advice because I feel absolutely terrible the past few days.
Note- I have been to the doctors recently for a routine check up and blood work and everything else was normal

 

I appreciate the response! I love the community here and ever since I’ve started (even though I’ve felt worse) I don’t feel as alone in my struggles.
