I imagine that you get your car serviced quite regularly, at least once or twice a year.
You do it without really thinking about it, while your car is still going fine - you drive it to the garage or dealership, pay a few (or many) hundred dollars, get it checked, the oil changed, a little tuning perhaps (whatever that means lol) then drive it home, confident that it won't break down until the next service.
So why wait until you suffer from depression, addiction, a relationship breakdown or anxiety to seek therapy?
Why not have a session or two when you are actually feeling quite ok, just to check in with yourself, make sure that everything is still functioning, nip any concerns in the bud, and work out the general direction that you would like your life to go, and what changes you'd like to introduce to make it even better?
In the same way that it is easier to drive the car to the garage rather than having it towed there, it is much easier to do therapy when you are functioning well.
It is more constructive to maintain mental health than to try and "fix things" that have gone wrong - especially when relationships are concerned, and you run a risk of them becoming "beyond repair".
So, are you ready for a check up?
