There’s the obvious answer, which is that there’s a difference between good stress and bad. I thought the good was called something like “eurkayotic”, but that’s not right. If you look up “eustress” that’s more or less what I mean.
But (and you of most people here knowing a good chunk of
my story), the good thing that happened as a result of my significant period of stress is that the stress ran free and eventually burned itself out. I found something to supplant it, and now I don’t worry about a damn thing. More than that, I’m happier than I’ve been in a very long time. I guess it always is darkest before the dawn.
In your case, I would say it’s probably a good time to suss out who’s voice it is inside you that is emotional and why. It’s an opportunity to air out a pocket of feelings, give it it’s moment in the sun and let it dissipate of its own accord. Knowing you to some degree, I think it’s safe to say you’ve been carrying these things for a while now. How much longer do you want to carry them?
I just finished rereading a book that among many things talks about the possibility of being beholden to something of an inner brat. The brat is protecting a buried dream or desire or inclination that was somehow threatened or shamed at an earlier point in life (generally childhood). The book suggested having a written dialogue with that voice to find out what it wants and is protecting and to give it a hearing so that one can let it go.
I would suggest having a dialogue with the voice that is unhappy with your life and let it reveal what its problem is. You can do this by dividing a page in half lengthwise and using one side for your voice and another side for the unhappy voice. Ask it a question, wait for the answer to bubble up and then give it due attention (and write down the response you get.) (@susanc also taught me this technique). If emotions come up let them. Find out what this voice wants and then decide if those desires or demands are still relevant. It may give you useful instruction to make a change of some kind, or it may be old reactions to old issues that you can let go of once they see the light of day and are deemed not so important.
Wish you well.
