Hi... You need to address these issues in a therapeutic setting. Grief Counselling is very much real and it is not like giving sympathy or something. It works at a very latent level and help the individual overcome their grief more effectively. No one can change what you have lost but the thoughts and emotions it created doesn't need to continue in your mind. It is okay to be an introvert, mental/emotional health treatments do not require a particular personality type to be effective.
Next Steps
Consult a Psychologist.
Grief Counselling is required.
