Someone with Obsessive Compulsive Personality Disorder is extremely concerned with perfectionism,and live by very strict routines and high standards. They feel like they have to control everything around them and others too- which obviously puts a strain on the sufferers relationships.
It can affect every area of their life, and interfere markedly with their career, education, social life and relationships/friendships. It is an anxiety disorder, and sufferers may also experience obsessions and compulsions (OCD).
It sounds like what you are experiencing is mild OCD rather than OCPD, unless there are any other symptoms you are experiencing? Lining objects up, from large to small, ensuring that items are straight etc and feeling extremely anxious are typical of OCD.
Go to your Doctor and explain all your worries, anxieties and symptoms, that is the best advice I can give. If it is really getting to you, then the earlier you seek help the quicker you can get on to the road to recovery.
