I feel lonely

Perhaps try thinking of questions you might want to ask. Most people love answering questions about themselves as long as they aren't too invasive/personal. Offer as much personal support as you can, no need for a lot of expertise, most folks simply appreciate the proverbial "shoulder to cry on" They are just grateful knowing you are there for them if need be.

You sound like a nice guy and I'm wishing you my very best. Good luck.
