I am agree with you. Some people might not find it easy to feel grateful, especially when dealing with tough challenges . In these situations, simply telling someone to be grateful may not be realistic or helpful, as their struggles could be complex and require more support and understanding.
Whatever struggle and complexities one faces, if you are not grateful for what has been done for you, there is no way you would get more. It's because of the complexity of the issues they are facing that would even make them appreciate every little help that comes because they know how long they have waited for that help.
