Think of it this way - You only read what people put out there in the message, right? So there's a lot of pieces to the puzzle missing. When someone's looking for support they aren't looking for someone to solve their puzzle, they are just looking for someone to say "Hey, perhaps if you turn a piece clockwise instead of counterclockwise, (i.e., using a method you may not have used before) it could change the outcome" or even asking a question to better understand where the person seeking support is coming from to open up the dialogue a bit more is all the support that person might need. Sometimes bringing up questions will encourage a new perspective in others. To give support, in my opinion, is simply to show that you are willing to put yourself out there in a compassionate way and to get to know a bit about another person, whether it's in one fleeting instant online or something that turns into a friendship.

The best thing about giving support is that you don't have to be confident in yourself to do it really, you just have to care about another person's well being. And after giving what support you have to offer, you may even feel better about yourself for doing it.
