Friend beating my ass

For context I'm a kaz main ranked around flame ruler with about 320 hours in the game my friend is a fujin lily/yoshi/reina main with 1000 hours. Whenever we play friendlies I want to play but after a few games I get my ass kicked. He reacts to every low, uses lilis 1 frame parry and beats me, then comes the handicapping, he starts picking sub characters, still beats my ass, picks my character who I've spent a considerable amount of time trying to improve on. Beats my ass. Picks a character he's played for 5 mins, after one set beats my ass. And by the end of the session I'm just malding it really feels like all the effort I've put into the game and my characters is for nothing because they can choose any character and within 2 sets be beating my mains ass. It probably doesn't help that I just swapped to stick, but I thought I was starting to get used to it. Then I procede to get demolished for 12 sets. It's super disheartening even though he has triple my hours I feel like I should be able to beat him. Any advice? With getting better or just dealing with getting my ass kicked
