Please contact a psychotherapist as soon as possible and although it becomes too hard to take the first step...

and there's a way to combat things right away and its great, you are helpful to yourself and aware!

Some steps I would suggest if u could manage..
1. Write all things down in a notebook..evrything comes to ya mind
2. Possibly try to write steps that can help to combat your symptoms
like...."if i wouldn't do that check..it's fine ...it will be..."
and leave the situation...think someting else
3. Say to yourself eveytime..(preferably write) about 21 times that
" I am a perfectly fine person...i don't care about the situation"
( Actually in human scale perfection is quite different from the situation of material world around..and we can't fix it evrytime)
4. Try to accept things....write affirmations...positive

Many times it will be frustrating..but do it slowly..it will help
