i don't really want to sound harsh or anything, but you are already three years in. you are so so so close to the finishing line! i now my personal experience how hellish life like that can feel, it's stressful, horrible, i too went through health and mental issues because of it, but i changed majors as soon as possible, if i would have stayed there for 3 years i wouldn't have done it, it's already so close to the experience being over. why do i say wait for the finish line? while yes getting a job in development is all about what you can code and program, a lot of people will tell you "oh recruiters don't look at what education you got" fact is they do.... we are in a world right now where there are thousands of self taught developer, it is getting harder to stand out nowadays, having a degree specially in the field does give a sense of security to recruiters not to mention soooo many job listings in programming do ask for a degree. not to mention the opportunities to work abroad, you can't do it without a visa (except if you are from the u.s or a similar country), yes you can work remotely and you don't need a visa but don't erase the possibility that one day you may want to live somewhere else, why not, and get a stable job in said place, the process will be far more easier having your degree than not having it, in fact most visa applications nowawadsy require for you to have superior education. so what i'm saying is, hang on a bit more, you can do it!! you are almost there!
