Hi, im new to here and looking for some advice and tips on dating someone with depression and anxiety

my girlfriend, i have known for about a year, and we started dating about 3 months ago. She was diagnosed with depression and anxiety shortly after we started dating.

I would be very grateful if anyone on here could help me with some general tips, help and advice on how best to support my girlfriend without smothering her and making her feel crowded - dos and donts.....

Any advice would be really appreciated
