Signs of obsessive compulsive disorder are various but may include restlessness, the feeling of a need to do something until it is done perfectly, repetition, thinking thoughts that you don't want to think consistently, a sense of impending negativity or even doom if you don't perform rituals, rituals themselves are a symptom of OCD, feeling unsatisfied after consistently accomplishing what you set out to do is another sign of OCD, these indicators are some good examples of things you might feel or do if you have OCD and if you do find yourself doing these things you could very well have the condition.
There are a vast number of people in the world that show signs of obsessive compulsive disorder, those people suffer from various types of irrational thoughts and behavior, for many it's bearable, for many it's hardly even a hindrance, slight ticks here and there such, but for some people it's all but debilitating, it causes such problems for them that it makes it very difficult to live life like a normal person.
OCD is something that can be treated though and can even be cured if you are willing to go the distance.
Do you have any family members that show signs of obsessive compulsive disorder? If you do you might want to take some time to learn about it yourself, that way you are better suited to helping them work through their condition, it will likely be a comfort to them, knowing that you understand what they are going through and that you have knowledge that can aid them in getting over their OCD.
There are various resources as your disposal to aid you in your research, some examples would be the internet and the library.
The internet is a great resource to research further the signs of obsessive compulsive disorder, there are a fair amount of symptoms that have been associated with OCD, the mind is complicated and everyone is different which has clearly shown through where OCD is concerned, the various symptoms of OCD can at times make diagnosis difficult seeing as how multiple symptoms of OCD can be attributed to other afflictions just the same, because of this you can be misdiagnosed, OCD is not an uncommon occurrence though and to take steps to treating and possibly cure it altogether certainly can't hurt so long as you take care.
Signs of obsessive compulsive disorder can be interpreted in multiple ways but the end result is that if you don't take control of it, it could very well take control of you and you don't want to relinquish control of your life to a mental condition that has a warped and misguided view of things.
If you are finding that OCD is a real hindrance in your life, I suggest that you take the steps necessary to correct it before it becomes much more than just a hindrance.
