Ever since her diagnosis my friend has isolated herself from me and from most of the other social groups she belongs to. She still goes to work and I have seen her chatting to her neighbours. She was very outgoing and very honest initially about the diagnosis but now does not reply to texts and actively avoids me in the street. I have written a couple of times over the past three weeks simply saying I'm thinking of her and here if she needs me. I don't know if I should do more and be proactive in getting her to socialise again (just a coffee or something) or whether to leave her be. I don't want her to think she's uncared for. Also I need help with my own selfish emotions of feeling cut off from her and missing her friendship.
