My depression and anxiety is going to be the end of my relationship!

So I’ve struggled with depression/anxiety since I was in elementary school maybe 8 yrs old ,it’s always been there have been on anti depressants on and off since that age I am 22 now! I feel like my SO doesn’t understand what I’m going through he says everything is fine and i should just “get over it” when I’m having a bad day ..

He says I should cut the bs and be there for our son when all I want to do is stay in bed all day

Any advice on making him understand that this illness is beyond my control ?

Why can’t I just be normal 😔
