Not perfect timing and I know it sucks - first, keep some things in perspective. Your husband loves and cares for you - I’m sure he is just as distraught (perhaps internally :)). Second, use this site during that time, keep in contact. Third, stay connected to your friends and family. Go for walks, drink rooiboos tea, get your nails down, watch funny movies. Arrange a time during the day where you and your husband can have a check-in - perhaps an evening Skype. Would your husband be open to writing you a letter of assurance before he leaves , one that you can read whenever and wherever? 2ww is a hard one, I’m in the second week and going a bit batty. However, I deep breathe, I carry a talisman that soothes my nerves, I have some acupressure points i hold, I go through a mantra. I can certainly offer an ear. You will be okay. You are a strong woman.
