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)
