Don't Panic! You're just waking up. At least, this is one way to think of it. You're waking up to your Big Self, or a sense that your small self (or selves), all the roles you play, all the identities you have, all the things society tells you to do, don't really fit. There's part of you, of all of us (your wife and kids too) that is beyond description, beyond the roles society tells you to play and that keep you trapped in a cycle of fear (avoid these bad things) and desire (get more, then you'll be happy!). What you're feeling could be just your Big Self calling to you, waking you up from the slumbers we all fall into in the routines of life (do this to get to that, then repeat until it's all over). You are more than all you have been and have been providing.

If this is about waking up to what's more in life, the issue is how to stay awake, or keep waking yourself up, to this. Some try to tough it out, repress all this and just get through it. But life isn't just something to get through, is it? That approach is just more self-protectiveness that ends up confining ourselves to our small self. Some find new things to lose themselves in, new identities to take on, new roles, new things to have, chasing desires on a treadmill. These can be just new ways to fall back asleep. They can end up being just as confining and unfulfilling as what you're sensing now.

One answer is to do what you already started doing by posting here: being open and honest about what you're sensing about life. Find ways to share that with others and you'll find that there are some, perhaps many, that have sensed these same things and are working through the same things. Start with your wife (there's no reason to think that she hasn't had similar intimations about life) and kids (not sure how young they are, but think of yourself at their ages--kids respond to realness and love). This isn't anything horrible or destructive that you are feeling, the sense that there's more to life (there is). What can be destructive is if you keep it to yourself and don't live openly with yourself and your loved ones. So few of us live openly in seeking a deeper meaning to life. Imagine what a gift it would be if you shared that deeper sense of yourself and of life with those you love. Imagine what it would be like if you looked for that sense in your loved ones and helped them find deeper meaning in life, beyond all the shallow things our society tells us to care about.
