Oh Red, I know it's hard to pull out of the scary thoughts...but you have to! You ARE tired, you've been through a lot physically and emotionally. The last thing you can afford to do is to shoulder the weight of what-ifs.
You ARE enough. You ARE tough. You ARE an inspiration. You ARE worth it. ((Hugs))
P.S. FWIW, sometimes I feel like my H and I don't have much to talk about on the phone too...but maybe too much is too much anyway. Keeping things a little mysterious can make reuniting that much more fun.
