People are different and the perceptions of one person may not be that of another.
I‘ve been in situations of having to leave "home" and going to another location for a period of time. You work with a new crew, eat, sleep, share tools, depend on eachother, and collectively solve problems. After a time, you go home and you notice that your preception of home, family, friends, and life changes. It isn‘t so much home has changed, but you have changed more.
Perhaps, by attending your BMQ, you enjoyed the comraderie and the collective structure. Coming home, you perceive that structure is not present and the people are not the same because your mind has opened. Plus or minus, everyone feels this to a degree at some point.
Remember that your family and your friends are you family and friends for a reason and those reasons don‘t have to change after BMQ. Have patience with them. They don‘t necessarily have to understand everything as you may not understand everything about them.
Also, don‘t think to much about the present. Things take care of themselves. Slow down. No matter what happens, you‘ll be somewhere tomorrow. Do well in school, get a good education, stay in the military if you like it, and use good judgement. Theres nothing worse than looking back into your past and regret something you should have or shouldn‘t have done.
If you get depressed and it seems no one understands you, and I‘m serious, eat a habanero pepper. Whole. Raw. Chew if you want too. Theres nothing in the world like it. Its a perception changer.
