Join the group,DEP-Leavin for bootcamp in May. You will meet others with loved ones leaving that day/week who may be in the same TG and have PIR together. Getting connected with others going through the same thing will help you to realize you are not alone.
Be sure to check out the discussion, Things to Do in the Last Month Before Your Future Sailor Leaves for the RTC. I also suggest you join Boot Camp Moms (and loved ones) and New Members Stop Here and check out the Pages (found under the pictures of the Members) and Discussions there, starting with OPSEC and PERSEC (Making Changes To Your Profile) and Arrival and What Happens at the RTC. Being informed will help you to know what to expect, which will reduce your anxiety about it and helping him prepare to leave and writing a short encouraging note to tuck in his wallet will help you to feel more in control since you will know that he is ready and has what he needs, which is mostly your love and support, but there are other things on the list as well.
Once he does ship, stay busy and begin writing letters right away even though you will not be able to mail them until you get the form letter with his address. Writing will help you to feel connected even though you won't get many letters or calls in return. Once you get that form letter, you will be able to start making plans to see him and you can join the PIR group for his TG. That will help you to realize that there is an end to BC and things do get better after BC because you will have more contact with your Sailor, but his time in BC will help you to realize that you are stronger than you thought and you both will make it through. You have raised a fine young person who will be pursuing his dreams to be US Navy Sailor.
