Pre-Diagnosis - waiting for blood tests to check for Lymphoma

Good afternoon. 

I'm looking for support or some advice, I'm currently waiting to have bloods done to check for Lymphoma. I'm 27 year old and have three children. I'm petrified. 

My current symptoms started off as a pea sized lump on my lymph nodes in my groin, then I started with night sweats, fatigue etc I'm normally fit and healthy. I have lost a lot of weight but within 1 month I have lost 10lbs. For the last 4 nights I've been having nausea, which only affects me on the night time. 

I just would like some advice/help. 

I have a great support system but I feel like I need some advice from people who are going through the same thing or have been through the same thing.
