You are not bad. Just because you are not the best player out there doesn't mean you are bad. There is always someone better and always someone worse. Complaining about it and not trying won't make you get better.
dude you use Hitomi. She has very very good mix ups and she can delay very good. Her ups and downs get into peoples head easily. And she has pretty good combo damage. Don't get predictable, switch it up. To be honest, i had this same problem but y'know what made me get better? I just watched some of those top players replays and stole some ideas. It worked fine.
It doesn't matter because when I face Sarah, Helena and Christie I'm pretty much a training dummy. Not to mention people counter hold every damn move I use.
You are too readable! Thats why they hold you. I noticed this, you fifinsh a string and whatever that string ends with, you'll use a move thats the exact opposite. For instance you'll do ppp then 6k. After the ppp they will hold mid k (depending on how many times you do it). Now, Im not saying stay mid because all nobs spam mid p hold but you have to make different mixups not just mid p mid k
