Alone vs. Lonely

They say we are born alone and die alone, and yes, it makes sense. But what do we define as "alone" and what do we see as "company"? In reality, are we ever truly alone once we come to this world?

I've been thinking about this during some of my practices. I was told once that my perceived "loneliness" is a trick of the mind. According to one perspective or point of view that exists out there (in some circles), this so-called sentimental "loneliness" is just an emotional state of someone who craves attention, closeness, and help.

Moreover, it's an illusion because we are always in the company of a multitude of things that surround us or live inside us - like our genetics, certain "programs" in our brain, generations of our ancestors (who are "dead", yes, but the definition of "dead" is a whole other story we would have to get into if we wanted to make these things a bit clearer), and some other entities.
Besides this, any living person is always subjected to intensive, careful surveillance by many processes and entities which he or she takes for granted or doesn't pay attention to simply because they exist in the world like inanimate, passive decorations... which is perfect for those said processes because very often they are NOT beneficial for our development and don't want to be seen.

We say "alone" meaning the absence of other people... but the absence of people doesn't guarantee that there isn't someone or something else all around us. This "loneliness" thing isn't something that's physically real then. It's something perceived (most likely emotionally) when we lack human/personal closeness, when we desperately require love, or when we are scared and need support. We are never alone because there is always SOMETHING surrounding and watching us, but we CAN FEEL lonely emotion-wise.

There is something that's very easy to answer, and I'll ask it as a rhetorical question.
Who do you think controls the situation - the one who watches, or the one who is being watched while living in complete certainty that his observer doesn't even exist?
