Hmmm... the phrase "friends for a season" comes to my mind when reading your post. Most of my friends came into my life at different turning points or pivotal times in my life.
I use to get upset that I don't speak to most of them anymore, but looking back I think they were briefly in my life for a purpose; when that purpose became fulfilled, we drifted apart or realized that we had nothing in common anymore.
I think it's hard to develop deep, meaningful friendship, especially at a certain age, and with our illnesses, but it's not impossible although it may take some time.
Have you tried meet-up groups? Often people make friends with those, who have similar interests or hobbies.
If your religious, you might want to try meeting people at religious organizations, i.e. church, synagogues, etc; I recently started going to church and am meeting new people.
Whatever you do, don't give up on making friends.
