When you are 'happy for someone' it means that you are happy that they are happy.
For example if your friend had fallen in love you may say "I am very happy for you."
Everyone is an individual and every person is unique so comparing yourself to others is not a good use of time, and it does often leave us feeling empty. It is better to look inwards and see what you can do to make yourself happy. This is a more positive approach to life.
happy for someone'とは、その人（someone）が幸せで自分も幸せなことを表します。
例えば、友達が誰かと恋に落ちたら、"I am very happy for you."（とてもうれしい）と言えます。
人はそれぞれ違うわけですから、他の人と自分を比べるのは賢い時間の使い方ではありませんし、むなしい気持ちになることが多いです。自分自身を見つめて、幸せになるために何ができるか考えたほうがずっといいでしょう。そのほうがより前向きに人生と向き合えます。

You can say that you feel jealous, since that is usually the feeling we get when we compare ourselves with other people. Saying we are jealous is not a positive quality when discussing serious maters. When we compare ourselves to others and are not happy for them, it can be taken quite negatively.
I can't always share in other people's happiness because I think of my own (unfortunate) situation
because of my own experiences, my heart is not always big enough to share in the happiness of others
