Same situation for me. I am single for a long time but recently many friends also break up contact more or less. They are founding families, building houses. I cannot really blame them. I am alone at home very often, most of the times it is okay, i don't really need someone in these times for talking and such. I'm not the big talker anyways. But there are some moments, especially in the evening, where the loneliness is just crushing. I always try to find a logical reason for this. In these moments i do not really feel the need for talking or meeting someone. It's a kind of fear to miss something because of the lack of friends. I'm for sure it's highly irrational and to this day I didn't find a definitve answer. Another observation i made is that these feelings are stronger when i'm hungry or thirsty. Sometimes, if i feel lonely i eat (i'm a twig, no worries). It seems to produce forgetti stuff in the body and the worries often go away. Browsing social media and stuff has the opposite effect. It raises the question "Why are the others having fun and friends and stuff?" Wouldn't recommend that (subjective) I'm sure there is a chemical explanation for all this, or an evolutionary, but for all ppl that feel like this: get your pizza! Of course this is all referring to the "negative" type of loneliness. There is another type which we may crave: "I want to go on top of that lonely mountain with nobody around me", "Let's go into the forest where no humans are going onto my nerves". This selective loneliness is a good one and should be looked for from time to time.
