Ok, I've had this for almost 6 years, I started only going in my house or my frinds etc, then the problem worsened and I could only go in an empty house. Recently my problem got even worse and I could barley go even when my house was empty. I had the usual side-effects such as slight eating disorder and the feeling that I just couldn't go naturally. My parents were understanding and I went to a physcologist, and in the end my paretns ended up going out for me every time I needed to go and everything was fine for a year or two. Then I met a really nice girl, and i realised that one day we probably will hav our own house etc.

What I did:

First thing I did was tell my family (mum dad brother)

Second thing I tried was actually eating things like bran and drinking orange juice all the time

Then I told my girlfriend and she completttley understood saying that she was sllightly the same in a way and knew many ppl who had it.

The most IMPORTANT thing to do is to become entirley open. Sit there with ppl actually in the room/bath/ shower whatever, even if u dnt need to go. Even talk to them etc (kinda funny, tho my dad is very open when he goes!) The point of this is to actually act out your worst case scenario, ppl actually seeing you there. Also (might be diffucult) make noise without shame so everyone can hear, allowing you to become comfortable and realise that NOBODY CARES IF YOU ARE GOING AS EVERYONE GOES!!

Also, never think about not going or how you might feel, be happy and beleive that you have the opertunity to go 24/7 if you want to.
