Hey there and welcome to deviantART!
I saw your artist's confession on tumblr. And seeing that you've only been here for a couple of days, it doesn't surprise me in the slightest that you haven't gotten much comments yet.
dA is a huge community and not being noticed between the hundrets of other new users in the first days, weeks or months is nothing unatural.
So don't put yourself down about it. You said to feel sorry for everyone who had to look at your art. That's not necessary because barely someone has even seen it yet.
If you want others to recognize you, then involve yourself into the community! Write comments to other people's works and fave the things you like, post in dA's forums and join groups! ^^
You could even work with other artists together by doing art trades or collaborations.
People will notice and appreciate your art when the time comes by. And I'm sure you'll get more comments and maybe even find new friends really soon.
I hope this helps a bit. ^^'
And if not, then there are still the other comments on tumblr.
Just don't give yourself up!
