DZ, please don't be too offended by what I'm about to write:

Likewise 

Can you please write clearly and to the point? 

That's what I thought I was doing but, please tell me then where is my sin in this? My grasp of Moral Theology and Moral Philosophy has never been that firm. 

Please, and be specific.

Thank you for at least trying.

Shouldn't everyone love themselves and rather be themselves that anyone else?

I answer that, There are two things in man, his spiritual nature and his corporeal nature. And a man is said to love himself by reason of his loving himself with regard to his spiritual nature, as stated above (Question [25], Article [7]): so that accordingly, a man ought, out of charity, to love himself more than he loves any other person.

This is evident from the very reason for loving: since, as stated above (Question [25], Articles [1],12), God is loved as the principle of good, on which the love of charity is founded; while man, out of charity, loves himself by reason of his being a partaker of the aforesaid good, and loves his neighbor by reason of his fellowship in that good. Now fellowship is a reason for love according to a certain union in relation to God. Wherefore just as unity surpasses union, the fact that man himself has a share of the Divine good, is a more potent reason for loving than that another should be a partner with him in that share. Therefore man, out of charity, ought to love himself more than his neighbor: in sign whereof, a man ought not to give way to any evil of sin, which counteracts his share of happiness, not even that he may free his neighbor from sin.
