I have been in a somewhat similar situation. I left my prestigious 4 year university midway because it didn't seem worth the money anymore. When I returned home to a local community college with the intentions of transferring after I had gotten all the credits I could, at first, it felt like a disaster. Every time I had to tell someone why I was back, or where I was going I got those disapproving and judgmental looks. Everyone thought that I had made the wrong decision, to them, it seemed as if I was throwing away my education, when in reality I am learning more and paying less where I am right now. For a long time it really bothered me and made me truly feel like a failure, that I should have just taken the financial risk and taken out all those student loans, but after a few months I began to realize that this truly was the best decision for me and whatever other people think is right or wrong, doesn't really have much to do with me, considering I am the only one that can make decisions for myself. I think what really helped me with that is reminding myself all the time of why I made the decision, why it is the right one, and shut my mind off to all the if's, and's, or but's.
There is absolutely no reason on earth why your degree would mean less because it came from a certain school. If what you have chosen is different, then so be it, I think you sound like an intelligent human being who most likely thought very carefully before making the decision and I would trust that! It's tough to ignore those looks, I know they kill, but other people don't walk in your shoes, so they can't really be the judges can they?
Walking a different road is hard, but if it's right, then it's right. I hope this helps a bit, sometimes it helps just knowing that there's at least one person who doesn't think you're crazy, because that's how I felt for quite a while until I heard a lot of these words from a very good friend, thank god for those. Hang in there!
