Loss of bag without any compensation.

I took a flight to Dusseldorf, Germany via Istanbul, Turkey on the 29th of April 2024 with Turkish airlines. I landed on the 30th of April, but my bag and the bags of almost half of the flight did not arrive. Due to the fact that we were so many people they could not deal with everyone on the system. They gave us documentation to fill in and promised us that out bags were already on the way and that we will get it delivered to is as soon as possible. I only had my medicine for another day as everything was in my bag, but never in a million years would I have thought it would not arrive later than a day. That was on Tuesday the 30th of April. I struggled to get information since then. Eventually I got a number of a courier service that supposedly had my bag. On Friday the 3rd of May I got hold of them and they said they knew nothing about a delivery for me. I then officially opened a lost bag query online as I realised I was not getting anywhere and by then I was already extremely sick without my medication. I managed to get some replacements, but did not manage to get everything so I kept on getting worse. On Sunday the 5th of May I even rented a car and drove from the Netherlands back to the airport in Dusseldorf, Germany where my bag no longer was and I confirmed that my bag was picked up by the courier services on the same say. I took a screenshot of the online record and send it to Turkish airlines again as well as to the Facebook messenger account of Turkish airlines as I have been trying to get hold of someone to assist me as I just got no response from them. The last time I phoned from a friends phone they said they have no records of me on their system as well. Note that I had absolutely nothing with me. I had to pay thousands for medication and had to buy clothes and toiletries again. At first only a rhing or two, but I had to go to London for work on the 7th of May until the 14th and then I was in Portugal until Saturday the 18th of may. I then had to buy all clothes I needed for work as well. All paid for with money I had not planned for and had to borrow money. I spoke to turkish airlines every day and they just did nothing. On the 10th of May someone suddenly dropped my bag at th place I stayed until the 7th of May. It helped me nothing as I was in London. I told them that I needed some kond of compensation as was extremely difficult with so little clothes and especially without my medication. I would have flown back from Amsterdam on the 24th of May, but due to my health I changed my flight to fly back earlier on the 19th of May. I had to fetch my bag so flew back from Portugal on the 18th and would have been to late to fetch my bag in time at the place they dropped it on the 10th of May when I already was in London so I stayed over. Got my bag and flew back yesterday and arrived today the 20th of May. I have had 3 weeks of hell without my medication and had to spend thousands just to look presentable at work as I had nothing to wear as well. Turkish airlines finally send a message yesterday asking me if I picked up my bag at the airport. I again gave them all of the information and this morning they let me know they will deliver my bag. This is no longer about a bag that I did not have for my full period. I need compensation and they just don’t do anything about it. This morning as I waited to board in Istanbul I even went to their customer care section and they just told me to go outside of the airport and report it again. They were extremely unfriendly and just told me to leave. Please help me as I no longer know what to do. Money will not fix the emotional damage they did, bit I have serious debt now due to all the extra money expenses.
