Questions: Family & Friends

I feel kinda worthless right now... and I feel a bit unworthy of my friend's attention. My friend and I met on the internet like 8 months ago. Started talking on a website, and then we eventually started following each other on our personal social medias (that's where we talk now).

My friend has left me on read a few times lately. The first time seemed to have just been a misunderstanding (but I got replied to half a day later). The 2nd time, my friend was probably just busy because I got a response to my text like 2 hours later. And this is it, I got left on read yesterday. Still haven't received a reply and it's been like 15 hours since then.

My online friend and I have some hobbies in common but now that I can see their social medias, I realize that it is a much different person from what I was expecting. My friend's popular, goes to parties, spends a lot of time outside... while I don't do any of these things and frankly, I'm quite a lonely person or, in other words, a "loser". And I don't know, it makes me feel unworthy of their attention. I always feel anxious whenever I send a message (I'm afraid of bothering/annoying my friend due to the push notifications). And I feel unwanted. Maybe my friend still cares but just takes me for granted, I don't know, but I feel very sad about the whole situation.

So should I stop texting my friend and see if they ever initiate? Maybe my friend will miss me someday (since we used to talk almost everyday for like 6-7 months). But well, my friend did initiate a lot of times in the past (on the other website that we used to chat). But not yet on the social media (though, we have been texting there for only a few days).
