How can you show your love for your friends??

I don't know if i'm a friendly person, but they keep coming home with me. My community visiting me when i'm lost or in pain or even sick. My friend used to keep me company and always wanted me to be with her when going out. My friend ask me advice and they feel like to speak more. I'm not a smiling person, i glance of smile will do when met, but the normal of me, I don't usually smile. But the only thing i do is to attend to their needs if available , go with them if necessary, listen and give my words for it, religiously do my activities for the whole week, generous sometimes, open to everybody. Same here, if secret is secret, it remain secret. They ask my opinion, and if accepted, they do. If there is things undecided, we still work for it. Is listening to a friend can be counted as friend.But i have a friend , through rise and fall she keeps me company, whatever i do she thinks i always can, whatever we share, she will not go if i don't come with her, she's transparent.I guess i found a friend, maybe i dont realize this until i found one.
