It's understandable that you are feeling lonely and isolated, and that you are struggling with depression. It's normal to feel overwhelmed when we are struggling with mental health issues and it can be difficult to know how to reach out for support.

It might be helpful for you to try to find ways to connect with others and build relationships, even if it feels difficult or intimidating at first. This could include joining a club or group that interests you, volunteering, or taking a class. It might also be helpful to try to spend time with people who are supportive and positive, even if it's just for a short time.

It's important to remember that it's okay to ask for help when you need it, and there are many resources available to support you. It might be helpful to talk to your therapist about your feelings of loneliness and see if they can provide additional support or suggest other resources that might be helpful.

It's also important to take care of yourself and engage in activities that bring you joy and help you feel more connected to others. This could include hobbies, exercise, or spending time with people who are important to you.

Please remember that you are not alone and that there is help available to you. It's okay to ask for support when you need it, and it's important to take care of yourself and your emotional well-being.
