It sounds like you're in a bit of a tough situation right now and although i'm not in your exact situation, i have anxiety so i understand. When my mental health started declining, i was doing awful in school, so i can imagine how much worse it is whilst in uni. I won't tell you exactly what to do but i think it's a good idea to spend a few days, a week or so etc evaluating your life at the minute and see what things are making you unhappy and anxious to see what you can do about it. If you decide to drop out of uni to spend some time on yourself and your well being, then good on you! it takes strength to do what is right for you. Of course you can stay in uni as well, which i think is what you'd rather do so in that case i'd recommend really exploring things that help ease your anxiety. You could always see a therapist if that's an option for you, otherwise there's plenty of support groups and people online you could try reaching out to. I personally find a creative outlet extremely helpful, especially when most of my schoolwork is very academic. No matter what you choose to do, remember that you're not alone and that you'll get through this, i promise. Hope i helped a little xx
