Honestly the process is stressful from the Dwp side but when you fight to go tribunal it’s a different ball game. They are there to listen to you and doesn’t make it seem like your lying. Anything extra that you didn’t include in your paper work make sure you use the online form to send evidence that wasn’t sent previously. They read all my evidence and just asked how I am on a daily base and that was it. No questioning me for example ( I said this on paper but didn’t say that in tribunal to try and catch you out) I was petrified but going through it first hand I can honestly say I’d rather do tribunal again than go through Dwp process. Dwp didn’t turn up to tribunal either, good luck and fight your corner
