If you speak Turkish, and English you will be able to find a job. But your salary is going to be way more lower then the UK, and most likely you will find it difficult to even live on in Turkey since you will be paid in TL not USD, or Euros, or GBP.
If you speak no Turkish then there isn't going to be many jobs available. You could try to get a job with a UK company that has a branch in Turkey, and get transferred over there.
2. You can try to get some certifications, and become an English teacher.
3. You can try to find an online job in the UK or a western country(USA, Canada, Europe), and then move to Turkey and do that job online since Turkey has good internet speeds.
4. You can try to start your own business in Turkey.
5. Or you can retire in Turkey.
Those are about your only options of work, or being able to make money in Turkey.
If you have a degree in the medical field that you could probably find work but without a degree in the medical field then it will be very hard to find it.
Also you fell in love with Turkey only because you where here for 1 or 2 weeks. But this is an extremely xenophobic country where many turks will try to make your life extremely hard here. Either because most of them don't know the laws, and rules when dealing with foreigners, or they simply don't want to deal with you because they hate non-turks.
For example you will say to yourself "Apartments are so cheap here" But you will find out that 90% of the people will refuse to rent apartments to you because you are a non-turk. I am an American and had this issue.
You will find out that if they are willing to rent to you they will try to charge you 2x to 5x the price of rent which you may find out may be the same price as rent in the UK, or close to it depending on what city yur living in.
It will be rare to find an apartment in Turkey with a good price unless if you do alot of searching around.
I have turks that refuse to put data on my phone because im a non-turk.
I have turks that refuse to set up internet service at my home because they said "im not a citizen of turkey" even though I called corporate multiple times, and they said there is no rules against that all I need is an ikhmet.
Before you make any move to Turkey I would suggest getting a friend in Turkey who can help you with everything, and who won't scam you.
