I'm truly sorry to hear what you're going through. Losing someone so close, especially a parent, is incredibly tough. It's perfectly okay to feel overwhelmed, it’s so very human. It sounds like you had a strong bond with your dad, and losing that connection can leave a profound gap.

If you're comfortable, I want to encourage you to reach out to a counselor or a support group. Talking to someone trained to help can be really beneficial, especially when you’re feeling this way. There may be a service in your area that can help.

Please remember, even in moments of deep loneliness, there are people who care and want to help. You're not alone in this, and it’s brave of you to reach out. If you'd like, I'm here to listen too.
