I see you posted this several days ago. So perhaps some of the decision-making, with regard to this has already occurred? I don't honestly know what to tell you about this. It's the type of quandary most, if not all, employed persons face at one point or another in their working lives. Do I leave a job I know I can do, but that I dislike, to go to a new more challenging job with better pay & risk the possibility that it won't work out & I'll be left with nothing? Or do I just hunker down & play it safe?

There's simply no real answer to this one way or another. You could take the new job & it could turn out great... or you could fall flat on your face. On the other hand, you could stay where you are & just become even more stultified. The good thing about staying where you are for the time being is that at least you have what is, apparently, a reliable income. Plus you have the opportunity to attend college on-line. (Of course this assumes you'd have the motivation & self-discipline to succeed studying on-line.) And, from what you wrote, it sounds as though you really don't have anything to fall back on if you were to take the new job & it were to not work out. It doesn't sound as though you have anything of any consequence in terms of savings. And you can't fall back on you parents.

You mentioned struggling with depression. One thing I guess I'm not clear about is whether depression is something you struggled with prior to getting the job you now have, or if it is something that has developed while you've been in the job. This may, or may not make a difference in the whole scheme of things. But, personally, I think I would be more inclined to encourage you to get out of the job you have now if it seemed as though the job was the cause of your depression. On the other hand, if your depression pre-dates your having gotten into the job you have, then it seems to me at least that it's more of a separate issue. (It still has to be taken into consideration. But, in that case, it's not necessarily like leaving the job you have now is going to make your depression disappear, if that makes any sense.)

Anyway... in the end... there's really no way I can suggest what you should do here. There are potential benefits, as well as pitfalls, to both staying in the job you have as well as to taking the new job were it to be offered to you. (Perhaps this option has already been resolved one way or the other?) I personally am a pretty cautious person. So I think if it were me I would probably stay in the job you have & start college. But that's just me. That doesn't make it the right decision for you. To some extent, I think perhaps one way to look at this is to think about where you want to be, both vocationallly & in terms of your life in general, say... 10 or 20 years from now. And then think about how each of these two options, or other options you may come upon in the future, contribute to achieving those long-term goals. I don't know if any of that is at all helpful. But hopefully I have at least provided you with some "food for thought", as the saying goes. My best wishes to you...
