<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello everyone! As mentioned in the title. I am a 23 year old man. I am currently at a point where I never leave my home, unless I have to attend a lecture, go to work, or shop for groceries.

This used to never bother me, but lately I find that I no longer get any fulfillment from my usual habits / hobbies. I am in short, disinterested in them, which leads to me sitting around doing nothing in my home.

Due to having been reclusive for a long time, since I was 12 years old in fact, and spending most of my time online, I am left without any friends to turn to.

I am not sure how to proceed from here. I feel as if it is unhealthy for me to stay solitary in my home, but I do not know how to go about meeting new people and making friends.

These issues are compounded by the fact that I am insecure in my appearances, and have pretty low self-worth. I cannot think of anything about myself that I would attribute as being "interesting."

Whenever anyone asks me what I do outside of work/school I have no way to answer properly, leading me to simply think that: I must be a very dull person.

The few friends that I did have must think I have contracted leprosy or something since after a very short extended weekend away from school they have stopped communicating with me completely, and begun avoiding me. 

There is nothing in my recent memory that stands out to explain why they feel they need to distance themselves from me.

To say I feel a little betrayed is putting things lightly.

I do not want to dwell on those things however. If they have any grievance with me they will make it known if they care enough. If they do not care, I am really forced to move on either way.

But how do I proceed? These friends were from school, so I have exhausted that avenue.
<bot>: Starting to feel lonely. Insecure about appearances. Low self-worth. No friends. Disinterested in usual hobbies. How do I improve my situation and meet new people?
