I have had so many experiences and i have learned OCD isn't a bad thing it's a gift. By having OCD you have so many amazing abilities and you can really make a difference.
When you have OCD there isn't anything wrong with you it's just that you are having fear and trying to escape reality. If you have dream every night about someone coming to your house and killing you that is not reality that is your belief and even if it does happen you can't control that you will just have to deal with it.
Also if you had to choose between loosing a leg or having OCD what would you choose.(think about it).
So here's my point OCD is a gift and you can beat it. Loosing a leg you can't change it, so just always think on the bright side and be in reality.
And i know You can beat OCD!!!!!!!
