I just want to feel like I'm living life rather than just excisting

Richard Briers' advice to budding actors was; "If you really want to be an actor, don't. If you really, really want to be an actor, don't. If you [i]need[/i] to be an actor, OK".
If you want to be a professional musician just to get away from a boring office job then you're not basing this decision on the right criteria.
I'm not sure what you think the life of a "professional" musician is, but if you think "existing" stops when you get your P45, you've made a big misjudgement.
Are you a very good musician, flexible with a great tone and ability? Do other people think you're as good as you do? What else do you bring? BV's, another instrument? Do you read? Are you regularly called up for deps and to join start ups? Have you got contacts? A lot of contacts, who are all working?
You don't have to look far to find fantastic musicians who are struggling to make a living.
Sorry, but I think you need a better office job.
