if you just want to do it because of money or a job or status (all externally driven) then dont do it. Your brain needs to change a lot to think as a developer. At the requires a lot of internal motiviation. If you dont have this, dont start. If you have this: lets go.

But you say about yourself:

I feel totally depressed and without enthusiasm

so I guess you dont have the internal motivation, so I wouldnt recommend you doing it. Maybe that changes when you do some projects, that you may need in reallife or projects that you like. Test around

I had enthusiasm and coded for 6 months straight when I had a team and real projects to go on during course, I really love and I am motivated when I have an objective and other people to work with, for me the problem is to study just for study, and obviously if I think I have to force myself to study alone I would love to know if the jobs situation is playble or as I see now industry search only for senior and experienced people (As I don't know how to make that experience outside of a job)

get yourself into normal jobs first. Maybe a junior, learn and work as team. With time you'll be mid and later senior and ofc you can always switch the company. I dont think you actually need to study to have a good job. Enjoy, have fun and deliver good results and you will be pretty fast in a good position

Are there any entry level jobs? Because I find only senior developer requests.
Where should I search? There are any particular platform? (actually I don't know if I can write here names of work search platforms)

It is safe to say that there are now almost no job postings for entry-level developers.
Especially considering the recent rapid increase in the number of developers, I believe it is better to change your major or choose a different career path.
If you are firmly determined to become a developer, I recommend giving the challenge of the AI ​​field a try.
However, while it is not too late to start with AI, it is also true that it feels somewhat late given the current age group.
Would you accept my friend request?

yea, there are many jobs that you can accept and many cool projects that you can do. Search on popular job market plattforms to get started and send out a lot (and I mean A LOT) of CVs out. Ofc improve your CV first and then send it out lol
