Who is really understanding anyway?

I feel like I can very extremely un-sympathetic....although appear very sympathetic and patient.

I have been told that I am very kind, caring, patient and understanding. 

I agree that I am kind and caring.

I disagree with the patient and understanding part...because I'm not.  What I am is just really good at hiding the fact that shit pisses me off quite a bit.

I do not have patience for a lot of things...I want things done a certain way and in a certain time period.  Because of that trait I have become one of those people that never asks for help and that has a very hard time delegating work or tasks.  I can just do it myself...that way I know its done right and in a reasonable time frame.

I'm also NOT understanding.  If someone is upset about something and I see their situation differently and see a better/easy outcome I am (inside) annoyed that they are upset.  I have NO sympathy for the person that handles situations in a way I feel is wrong. 

I have a friend that is going through a divorce.  I feel that she is unrealistic with the outcome she is expecting from her ex/lawyers and even the judge.  I've been through a divorce...I have some ideas as to what happens.  Side note...I never claim to know everything.  BUT my friend comes to me with questions/stories/advice.  I don't think she every really likes my answers.  She then goes to her family with the same questions/stories and advice...and always gets different answers/advice.  From her family, who is much more sympathy  I think she gets the answers she wants to hear....rather than reality.  Which in the end does turn out to be the fluffy answers and not reality.

I have another friend who when things fall apart and something upsets him, he drinks.  That's how he copes. I don't understand that...and it annoys me.  I have no sympathy for the situation at that point nor care to even be around him.  I just distance myself until it blows over.  

I also don't understand addiction...and I don't feel its a disease...but that is going to have to be an entire separate blog post on its own.

I hate having to rely on anyone for anything.  I usually end up disappointed. 

What does this say about me as a person? 
My friends/family feel like I am great support system and I am always there for them...I feel like a sham...a liar...because half the time I don't mean it.
