Hi aniya,
Hey, it's OK. you've got good parents. tell them you appreciate their love and caring, by word, gesture, roses, whatever works. That should deepen the communications channel even further for you to let them in to your innermost feelings. They probably already know, and are waiting for you to affirm it by bringing them into your circle of relationship. Parents tend to have this sixth sense about them. Sometimes, they know before you do.
Your therapist may be able to suggest a few methods of how to do this as well.
Take the pressure off yourself, and just know they love you.
Let us know how you are coping. Best of luck (Labouring Under Correct Knowledge)
Be safe, well and happy.
Lotsa huggs
Catherine
