Welcome @Meg1112 - it is good that your have reached out and I am sure you will receive lots of support here. Someone will have your diagnosis and you will feel less alone.
Yes, it is a real shock to us all as it is not something one expects. Do you have support ? If this is really getting to you do contact a counsellor (one may be available at your treating hospital) or contact the BCNA helpline on 1800 500 258.
Someone in your area will no doubt also be in touch with you and they can assist with more localised suggestions.
The waiting is the worst through each stage of this disease and treatment. Some people join in with groups, some enjoy their sports or hobbies, some are involved in music - whatever makes you feel a bit less alone and takes your mind off it a bit.
Try to take things one day at a time and don't overthink things - and no Googling as the info may not be accurate and may not be relevant to you.
Thinking of you. 💖
