I understand why you're angry, and maybe it's helped you a bit to vent a little, but you need to take constructive steps to make the best of a very difficult and unfortunate situation.
These are the actions you need to take, do them step by step:
- Remember, you are in the same accommodation and attending the same course as thousands of students before you. Money-wise, you are no better or worse off than they were.
- If you do want to go home, speak to your Uni's accommodation department. See if you can cancel your accommodation contract. If not, remember the above.
- You are getting your education. Presumably, you are taking a worthwhile degree with good prospects. You are in a very good position and with hard work you will go far. But you DO need to put in the work - you are in first year so there is a bit more wiggle room, but you do need to make sure you get a good foundation
- This means that you need to take your work into your own hands. Do the assigned reading and homework. If you don't understand something, email or schedule a video call with your tutor with specific, clear questions. If you are still overwhelmed, email your tutor asking for good starting points and resources to help you.
- Make sure you watch every lecture in a timely manner. This is one of the most important things you can do for success.
- Try to get into contact with people on your course. It helps a lot to study together, you can bounce ideas off each other and help each other with the content/assignments
- Reach out to your university's pastoral support if you are still feeling very overwhelmed
- Register with your Uni's GP and make an appointment with them if that doesn't help
- Try to get into contact with friends/family if you can. Talk through things with them, sometimes it helps just to say things out loud.
- There are other options if you go through all these steps and are still feeling like this. You may want to take a gap year, switch course, switch Uni, or even drop out. At the end of the day, this is your decision now. It's your life.
Good luck.
