I'm really sorry to hear that you're going through a difficult time. Taking care of a kitten can indeed be a significant responsibility and might not be the best thing for you right now, especially if you're struggling with depression and anxiety.
Here are some steps you can consider taking:
Reach out for support: Talk to someone you trust about your feelings, such as a friend, family member, or a mental health professional. They can offer understanding and guidance to help you through this tough period.
Seek professional help: If you haven't already, consider reaching out to a therapist, counselor, or psychologist. They can provide valuable tools and coping mechanisms to help you manage your depression and anxiety.
Contact the seller: While it might feel difficult, you can reach out to the seller and explain your situation. They may be willing to take the kitten back or help you find a new home for the kitten where it can be well taken care of.
Look for a new home: Try to find a responsible and caring person who would be willing to adopt the kitten. Reach out to friends, family, or local animal shelters to see if they can assist in finding a suitable home.
Temporary foster care: Some animal shelters or rescue organizations offer temporary foster care for pets, especially during difficult times. Consider contacting them to see if they can provide assistance until you're in a better position to care for the kitten or find a permanent solution.
Be gentle with yourself: Remember that it's okay to acknowledge your limitations and focus on your well-being first. Taking care of yourself is crucial, and it's okay to ask for help or seek alternative arrangements for the kitten.
It's important to prioritize your mental health during challenging times, and seeking support is an essential step towards healing and recovery. Remember that there are resources and people available to help you through this, and it's okay to ask for assistance when needed.
