I’m really sorry you’re feeling like this—it sounds so draining, and I can see why you’re questioning it all. The WhatsApp situation seems like it’s been blown way out of proportion, and I get how isolating that must feel. People can be so quick to judge without understanding.
As for the degree, you’re right—plenty of people succeed in jewellery design without one, but the course could still help with networking or structure if you think you’d benefit. Maybe talk to a tutor or support staff about how you’re feeling—they might have options you haven’t considered yet.
The loneliness and dark thoughts are really worrying, though, and you don’t need to handle this alone. Reaching out to someone, even a counselor at uni, could really help. Whatever happens, this situation doesn’t define you, and there are other paths if this one isn’t working.
