Letter RE PIP decision.

Sorry for starting a whole new thread on something relatively small but I can't find my previous threads!

I received a letter today which was dated 18th April saying the DWP have 'all the information they need to make a decision on your PIP', and that was it. so a complete waste of paper.
What I don't understand is that on the 8th i had already received a text saying they had received my report from atos and would be in touch soon with a decision,the text said up to 6 weeks. So why have I got a letter dated 10 days later saying almost the same?!
Also how long after receiving such letter will I be waiting till I finally get the decision?

I got exactly the same letter in the post today. I was told at my assessment it would take 6 weeks for a decision to be made and receive notification of award or not.

I havent heard anything more yet but was at my Doctors today and she said she had not been contacted regarding PIP.
Is this normal? I presumed they always contacted your doctor to gather 'evidence'. And also presumed thats why it takes so long!

It's me again, just a quick question.
The assessor seemed interested in my OCD. (Probably the least of my issues, or so I thought) . They were asking about showering / bathing and returning to shower / bath several.times in a day as well as obsessiveness about appearance.
I presumed i was going to score 0 for the washing part of the assessment as I can do so on my own without prompting. However, someone has told me you get points for overwashing/ocd. any idea if this is true?!
Thanks
