Hi Pedro, I think you are in a great place. Many people help others, but they are not in the place you describe – everything being right – so they must work with this challenges – health issues, family relationships, depression. You, on the other hand have your immediate joy for living to give, which is so needed, at every corner. Take some time, perhaps ten minutes a day, to look at these questions from a spiritual perspective. What are you being asked to do? Usually, we can start with what is right in front of us. Who could use some tenderness or encouragement? If you focus on helping those in your immediate surroundings and you still feel ill at ease, perhaps you are being called to work some where, where there is great need. Certainly these big questions should be asked along side with prayer and spiritually reading, especially the bible. And keep asking people. Ask here. That is a good start, but ask people who are living lives of service whom you admire and respect.
