This is me pretty recently. The missionaries in my ward really had no idea, but they did ask me to give people rides places, and that ended up leading to a ton of good for me. One of the reasons for that was feeling legitimately helpful to people. If there's something you genuinely need help with, asking a struggling friend for help with it could do them a lot of good. I'm not going to say it's the case for everyone 100% of the time, but it absolutely was for me.
