Get two journals. One should be a graditude journal that is for others to read. Every time you have a thought regarding love, thankfulness...etc toward someone you love write it down. Then when they come home, over, they can look in the journal to see your thoughts. Or you can look in the journal to remember your thought and tell them when they come home, over, etc.
The other journal is for you to remember what you feel, good or bad. It is not for others. It can be poems, prose, or just thoughts. It will help.
And take one day, or one hour at a time. You will get through this. With the help of all your loving ones one day at a time, you will get through it. When times are tough, read your graditude journal and remember all the good thoughts you have had.
Good thoughts. W.
