Hello not sure where to start so I'll jump right in, sorry if this is the wrong place to post wasn't sure where to categorise it. I'm 23 and have been having issues for a long time (a badly long time) such as nipple discharge in one breast but put it down to period cos it only happened when I was on that. But a while ago I found what I feel like was a hard painless but smooth lump which feels like it's on my rib right by my cleavage, now I have health anxiety so I tend to think everything feels like a lump, but this one felt real, then over lockdown I've noticed my breast looked so much smaller (it's always been smaller but not noticeably) but I've been (deliberately) losing weight so thought that. Anyway yesterday I broke down and told my mum and she made me make an appointment, I was seen the same day. The doctor I saw seemed very unconcerned due to my age and lack of breast cancer history in my family, but she did the examination and felt the lump I mentioned but also another one which I didn't realise on the complete other side of my breast, so now I'm worrying about that. She referred me to breast clinic but kept saying that she didn't think it was cancer or anything bad but don't really believe her as what can she tell from just an exam? Anyway I just am so so convinced I'm going to be diagnosed with it and am going to die young. Also after she mentioned the other lump I now remember that I felt sort of bruised pain in that area for a while but didn't realise till after appointment so now thinking I should have mentioned, can't stop prodding myself and worrying and googling and thinking how I've wasted my short time on earth. 

Also very anxious about the breast clinic as I don't want to do it on my own and I know I probably will have too because of COVID. Has anyone else been during this time?  
Will they scan my whole breast? I'm worried about this second lump now, I still can't feel it but feels like a thickening, kind of ropey with lots of lumps? What if they don't check that? 
also know that my doctor has marked me as health anxiety on my notes so they will see that and might not take me seriously? 
doubt anyone will read all of this but I needed to get it out my system.

*Edited as got results*

Hiys so turn sout my lump i found was a fibroadenoma, and I have another one in my breast too, and the ropey thickening was a biiiiiiig cluster of cysts, which I also have two of. So I was overreacting but thought I did share my results so if anyone has similar symptoms this could give them hope Doctors aren’t doing anything about their findings just told me to be more vigilant and come back if I notice anything new.
