Feeling Isolated This Eid... How Do I Find Peace?

Assalamu alaikum. My family doesn't really practice Islam; they follow cultural traditions rather than the teachings of our deen. It's hard to ask other Muslims to include me because I'm worried they'll see how alone I am, and honestly, I don't have a big circle of friends anyway. I never know what to do when Eid comes. It always brings me down, seeing everyone outside celebrating with their loved ones while I feel so by myself. Any advice on finding comfort and dealing with these feelings?
