I can relate to you only to a certain extent. I grew up in a strict family too and I understand what's like being pressured with a deadline and what's is worse, being afraid of not meeting your own expectations. I grew up kind of afraid of failure. But I developed some hardcore personality, because I end up giving my own blood so I won't fail. And if I do fail, I'm ashamed of myself and I end up trying even harder. There's a downside of being like this, but let's not talk about this right now, since this is about you.
Say, for example, would you shut yourself in a room, spend the whole day immersed on your project, not connected to anything? If you can, do it like this in 7days and you will have it finished. But if you can't be like that, just accept it. Accept the way you are. I think the secret is to adapt your work to your lifestyle, and not the other way around. It's just that to me, it seems that what is really blocking you is your fear and your expectations. Drop the fear for now. Block it, keep going and just stop that negative thoughts somehow (I know it's easier said than done). If you don't meet your expectations, try harder in the next project. You keep improving as long you don't give up.
I'm sorry I'm not making any sense right now. I'm really trying my best to keep myself awake and write a decent text here
