I will reply to you since noone else have.
First: I believe many people, not just you, are unhappy with their work. For many (most?), it is just a way to keep life going, fighting monthly expenses. Most of them just keep on going in their treadmills. I would say you are one step ahead, since you have started to think/reflect upon it.
Glad you are happy in love. Many people haven't found that luck. But love can materialise in many ways
Meaning of life... THE question we all long for the answer to!
Again: Many people ask that question: Few do something about it. They just keep on doing what they always have done. Remember: If you keep on doing the same things all the time, you will receive the same results all the time...
Spending time with oneself: Now you are on track! The Camino is a fantastic way (!) to ponder your life, think, reflect, and maybe receive completely new angles onto your life. But the Camino is a hard walk: It is not easy. You may experience pain, exhaustion, tiredness, depression, not reaching your goals, etc. But you have found a great forum here: People more eloquent and experienced than me, and with more insight, are posting their reflexions here. Read as much as you can. But don't expect the walk to be a romantic one: Rather, a journey into yourself, crossing beautiful landscapes in rural Spain, but not without effort and maybe some pain..
By walking, and coming out in the other end (Santiago), you will (hopefully) have learned a lot about yourself, your closest, values of your life, and what you are capable of. And you will have found new friends. You have also done something active in order to get more insight into your life and yourself. It is worth it.
I can only speak for myself: After 3 caminos, I have found ideas of how to completely change my life, and I most likely will, in the near future. I got the insight while walking my Caminos. It took some time, but now I'm nearly there.
IMHO, the Camino is not a quick fix for your general problems, but you may be surprised by all the life-changing solutions it offers while you are walking, and not least, when you realise what you have actually achieved at the end of the day... It might just set you free...
