We all need company some of the time. Finding it when you want it is the problem. Not just anyone will do. You want a companion who treats you as a person with a mind of your own, who values you,is concerned about you without being intrusive, or at least shares some of your interests. If you are with someone who tells you how to live, but gives you orders, talks down to you, then you may feel angry, depressed, become even more lonely. Maybe, like most of us, you would sometimes benefit from some diplomatic advice. But generally we think and act more sensibly when we can have calm sympathetic discussion with a person whom we feel is on our side, wants to understand our point of view and is not going to judge us for the mistakes we have made, and may be likely to repeat.
If we are very lonely, we may be so desperate that we are vulnerable to the suggestions of anyone who bothers to notice us. Torturers and bullies use solitary confinement and social exclusion to control their victims We need to do what we can to stop that. Here we are talking about loneliness caused by negligence. You might be lonely and feeling neglected; maybe other people neglected you so you neglect yourself. If you try to seek help you might be advised to learn social skills like listening to people. Stuff that. Like as not you are trying to get away from people who just want you to listen to them. And if you just want someone to listen to you, play safe, talk to characters you can trust like horses. If you want to mix with people think about getting involved with activities, like joining a choir or doing a course to learn something. You could walk to the library because that is where the info is and librarians like having visitors. They might encourage you to join a reading group. Compared to sitting alone feeling sorry for yourself it might turn out to be fun.
