Yes, I've done that, to an extent. I've kind of used travel as a cure. What I've found is that while geographic escape may distract me from some of my problems, it doesn't fix them. It turns out that I have to actively work on my issues in order to resolve them. I've also occasionally dumped a lot of time/money into hobbies and then wasted the opportunity because I was not in the right frame of mind to enjoy it.

So, in hindsight, I wish I had started to actively work on my problems earlier.

A few weeks for an appointment is not long at all for those kinds of things. Can you get on the waiting list and start learning Portuguese while you wait?

Any therapist who just tells you to go get a hobby is probably a bad one, btw. The point of learning Portuguese is learning Portuguese and the point of therapy is addressing mental health issues. The rush can be an unhealthy motivator in the long term, especially when it comes to romantic partners
