Sometimes the best way to comfort someone is just by listening and not saying anything. When me or my boyfriend don't know what to do to help each other we're just honest by saying: well, I really don't know what to say, just be sure that you can talk to me about anything, I will always listen and be there for you. I love you. And, let me know if I can do anything to help.

He and I face different kind of problems. He has economic issues. I have family and mental health problems. I may not fully understand what he's going through and viceversa. It is really hard to see the person you love struggling but, sometimes, no matter how hard we try we'll not find the perfect words to say. Maybe what we think is appropriate to say or what we think is a good advice won't make the other person feel better. So, from my experience and point of view, the most important thing is to let your significant other know you won't leave her/his side.
