I'm relapsing but I don't want to tell anyone
Why don't you want to tell anyone?
Because it will be too stressful to tell anyone about it.
Even if you are afraid it will be uncomfortable, you should tell someone if you are relapsing and you need help.
I know that but I don't want to be judged.
I can't imagine anyone would judge for something you can't help. Relapses can be difficult and it would be good to tell your friends and family so you will have a support system when you are feeling your worst.
