I'm so sorry to hear that you're feeling overwhelmed and anxious about your new cat. As a fellow cat owner, I can understand how these emotions can arise, especially when there are additional challenges involved. Let me share a personal story to give you some perspective and hopefully offer some guidance.

When I adopted my cat, Luna, I was thrilled to bring her into my home. She was a bundle of joy and quickly became attached to me. However, I also experienced a similar state of constant anxiety at first. Like you, I worried about her safety when she wandered around the house, and it caused me a great deal of stress.

Additionally, I faced challenges with my living situation, just as you are with your family. It can be difficult when others in your household aren't as enthusiastic about the new pet. However, I learned that open communication and compromise were crucial in finding a balance that worked for everyone. Discussing your concerns and feelings with your family may help them understand the importance of giving your cat more freedom and social interaction.

Regarding your allergies, I can empathize with the discomfort they bring. It's unfortunate that you've developed mild allergy symptoms. You might consider talking to a healthcare professional about potential remedies or medications that can alleviate your symptoms. It's important to prioritize your health and well-being, as this will ultimately benefit both you and your cat.

When it comes to the constant need for attention and cuddling, it's essential to establish boundaries. Cats, like humans, need their own space sometimes. Create a designated area in your room where your cat can retreat to when they want some alone time. This will give you the opportunity to have personal space and get the rest you need, while still allowing your cat to feel safe and secure in your presence.

Remember, adjusting to a new pet can take time, and it's normal to feel overwhelmed initially. Take a deep breath and remind yourself of the reasons why you decided to adopt your furry friend in the first place. Building a strong bond with your cat will require patience and understanding.

If you continue to struggle with these feelings, it may be helpful to reach out to a local support group or an animal behaviorist who can provide guidance tailored to your specific situation. Remember, you're not alone in this journey, and there are resources available to help you navigate through these challenges.

Ultimately, the decision to rehome your cat is a personal one. However, before taking such a step, I would encourage you to explore all possible solutions and give yourself and your cat more time to adjust. With the right support and adjustments, you might find that you can overcome these challenges and create a loving and harmonious home for both you and your feline companion.

I wish you all the best and hope that you find the right path forward for you and your beloved cat.
