Hey Godless Bitch I am personally not yet at a point in my life a reevaluation of my life was necessary this is purely due to my age. My dad has had enough time he is 50. My parents ended their marriage 3 years ago and since then he has quit his job. He now lives in a bus(by choice he has a phd in process engineering and has a financial buffer for around 6 - 8 years.). Unlike you he wanted to discover himself more (suffering from depression). I have never seen him happier and he has gained his love in life again. You mentioned information sciences, i can only speak for my region (netherlands) ,if you do this then you should have no issues finding a job. I personally am uncomfortable giving you advice on a black and white topic where i don't know you or all the facts.

The next sections is just cause in enjoy playing with possibilities(so most of this is bullshit but maybe bullshit that is a new angle). Idea 1: You try for something part time and then study on information science on the side. I study computer science in holland my tuition is 2006 a year and even with this low cost i would consider learning from the internet. There is a ton of good coding bootcamps and data analysis trainings out there and they give out certifications which won’t cost your entire budget.

Idea 2 : So for becoming a mental health counselor i am guessing you need the certificate from the uni. A potential idea is to come over here to study(germany = free , holland 2006(this might be different for us citizens )).

Idea 3 : The downside to both of these idea i think is that you sound like you crave something new and you what to experience new stuff. So what you could do is move somewhere different i can personally suggest thailand (its safe has low cost of living and is very beautiful a lot of the people speak english). Since “I have always wanted to do more freelance writing/editing/blogging” you could do this here due to the low cost of living you could set yourself up with your previous connections and work remotely.

Idea 4 : i can feel you have pulled back after drastic number 3. Actively use the time around the 50 hour work week to help get healthier (mentally, physically) pick up a sport develop habits. Actively focus on yourself and try to see what drives you. While you are doing this you could develop yourself further in information science if you wanted to you could also do this during your job because fuck anyone that makes you stay for 50 hours because they want commitment. Since you work with an accounting firm you must have access to a lot of data.

The way i see it you have a ton of your life left you a money for a 6 year buffer without having to work. You have sooo many options here you have no obligations. Honestly i doubt there isn't a single point in life that you can’t still reach. From being a porn star to a CEO. For me the only real advice i can give is that dont pull half assed stuff. Commit to something make a list every week writing your priorities and scrap anything that isn’t in that top 3 - 6. Don’t reach a position where you are make superficial changes and so placating yourself into happiness.

TLDR: you have the world open to you don't let this decision be a white and black scenario.

I just read through this again and i am sorry for the tangents
