I feel so lonely

Ever since my breakup, I just completely lost my spark. My social circle has been shrinking and I’ve spent my holiday just staying at home by myself. I’m not sure why but so many people have been ghosting me and I don’t have that many people to talk to compared to before. I used to be more extroverted but now I just sit and eat by myself. I’ve an assignment due and I’m not even sure who to ask help from…whereas back then I could’ve easily gotten help from my friends.
