Pressure to move forward

I (45m) lost my wife (45f) to breast cancer 3 weeks ago. I am grieving with my daughters (17 and 20) and we are going to get through it together. For the last week I can’t get the future out of my head. When I look at my immediate future, it looks very lonely. My oldest already lives with her boyfriend about an hour away. My youngest will leave for college in about 18 months. We have an 11 year old dog and a 14 year old cat. I figure in under 5 years every remnant of our family will be out of the house or gone except me.

This concept terrifies me and makes me feel like I need to dip my toe into the dating world asap. After being part of a committed couple for over 25 years I don’t like that idea. I’m a mess, I know this. I wouldn’t be good for anyone right now and I have no capacity to add another family to the mix, but knowing that doesn’t help the feeling of impending loneliness. Finding people who are in the same boat to talk to is almost impossible.

Sorry, just venting. Guess I just needed to get it out.
