Hi km... you are not alone you have all of us here to reach out to. Talking through how you are feeling with others can be very helpful.
The other idea is to then get out of your house. Run an errand, go to a coffee shop or a store with a food counter. Browse around and shop or just people watch. That will take your mind away from being alone and you may even strike up a conversation with someone else sitting nearby. It's really helpful if you can make a habit out of going to the same place for a coffee or hot chocolate or an ice cream so that the people working there get to also know you as a regular and you will be greeted as a friend after awhile.
Keep posting and telling us how you feel. What you are working through takes courage and strength and energy. It can deplete you so give yourself a break and be nice to you.
Thinking of you
