It is good to be humble and know how God our Father is the One who really cares >
"casting all your care upon Him, for He cares for you." (1 Peter 5:3)
So, trust God about this; God does change us so we share with Him in how He is caring.
Transforming hearts is what God does, so praying is important if you notice you are lacking compassion for others.
And as God changes us, also we can use our sin failures to help us feel for others and what they are going through in their sin problems >
"He can have compassion on those who are ignorant and going astray, since he himself is also subject to weakness." (Hebrews 5:2)
I did a social skills test and got 18/100
Now, of course, in the United States married American couples have had more than a fifty-percent divorce rate > this could mean there a lot of Americans have social skill issues. So - - what if ones of these are the ones giving you the test items????
I mean, ones testing you might not really know how to love, themselves. Even so > I read some Asperger's things and I was stunned how many went for me. But . . . in my case, what I noted was how so many were about how I can be so into myself and not caring about others as myself. And I can be not feeling for others, but making people mainly theoretical and with one-size-fits-all ways of seeing people. So, in my case, it was clear I had problems deeper than only a brain thing; I needed how God alone can change us to how He has us loving.
But even if a secular person can point out things about me, this does not mean that person can take me where I need to go. Only God is able to change me to how His word says to love.
So, may be you will do well to see how God's word says to relate and communicate. There is plenty in the Bible to help us find out how to love. I offer how every scripture can be used by God to help you find out how to relate and share in love. And Jesus makes us strong and wise, so we can keep on loving when others reject us and do not understand us and avoid us. His love makes us deeply sound, but still caring and ready for love, so we are best friends of unloving people, by being their good example of how to love.
There are plenty of people who do not know how to love you. But with Jesus we can be their good example, but while we keep seeking God for real correction.
God's love is where all of His word is coming from. So, any scripture has God's love meaning.
And love isn't only about skills, but how we become in sharing with God.
There are people who seem to be one of the most intelligent, charming, Jesus-talking people around. But they can not handle being in a marriage, can not tell the difference between who can and who will not do well in marriage. And yet they can think they should be mentoring everyone.
So, your adventure includes finding people who are true examples for Jesus. Even a lot of very smart and educated and socially accepted people have not been able to do this. But God loves to help people who know they are helpless, and love
"hopes all things" > in 1 Corinthians 13:7.
So, yes you do need to care about people, and have hope for anyone, at all . . . including yourself; because Jesus God's own Son suffered and died like He did, on the cross, with hope for any person, at all. So He wants you to share with Him
