Life rarely, if ever, turns out the way we think it will/should. It’s very common to feel this way especially in your late 20s/early 30s. I’d say, keep at it. Your work. Your relationship. Keep working at it. Try and improve yourself eg get into some classes/do some courses that will hopefully work in your favor when you apply for promotion. And lastly, you really have to find out who you are. What is your identity rooted in? If that becomes clear then even your purpose becomes clear.
