A bit of a background.
I'm a physics student and at the end of September I will finish my Thesis and get my 5 years degree (1 and a half year late). I have done my graduate studies with a specialization in Theoretical Physics. Even though I've gotten through my degree with the best possible grades (that's the year and half) I've realized too late that physics it's not what I want to do and, of course, this has brought me to study just to pass test and not to understand physics making me very bad even at things that I should know (It is apparent to any physicist who talks to me for more than 5 minutes, like the supervisor of my thesis). Knowing now myself I would have loved (and probably I would have been much better) taking an engineering degree.
So now I feel without any option left, having acquired 0 marketable skills. Should I go into a PhD hoping to find something more engineering-like that I could like and could lead me to have a job in the field after it? And even if I find it I'm not really sure I could take that position given my lack of understanding of even the basics of physics (imagining myself having to take teaching duties on things I barely understand is laughable). The other option is to stop here and try to find an admittedly enjoyable coding job (that's the most technical job one can get with just a Physics degree) but it would still require me months of studying to have a chance in a interview. As a last thing, I'm 26 years old and not having any financial income it's quite a burden so this add to the list before.
Honestly, I feel like choosing a physics degree ruined my life and I don't know what to do.
EDIT: To be more clear, I don't want to be a Physicist in the sense that learning for the sake of it it's not something that I want to do, so research is a nono. If I find a job as a, say, software engineer I would not mind expanding my knowledge to which I would see a practical application to. What are my options (I don't mind to move around the Europe) at finding a job using my physics degree. Possibly a coding job (as I said, it's quite enjoyable). Or, could pursue a PhD be a good choice to get more insight in some field of engineering (It's the only way that I see to acquire marketable skill), so that for when it's over I could use these skills to work in the field? For example, all the people that I know that completed 5 years degree in either computer science or electronic engineering got a job (in their field) in less than 2 month from their degree.
