Embarrassed and missing my ex

Since it’s Sunday it feels weird to be completely alone right now. I don’t have anyone to talk to, no one to see, and nowhere to be. Usually he and I would be making plans or hanging out already. I miss having a partner and a companion for days like this. I’ve got pretty bad hangxiety going on today, and usually a nap with him and the dogs would cheer me right up. But now I’m just feeling so sad and alone. It’s too quiet in my apartment and I don’t know what to do. If you have any suggestions to help me get out of this funk today that would be great. I don’t want to keep crying over him anymore. I need to learn how to be alone again and it breaks my heart.
