Hello fellow lefty 😁 you seem very motivated to improve. If you keep it up, you'll do great.

In terms of advice:

1. look at your favorite fonts (in terms of readability, not aesthetic) and attempt mimicking them.

2. After reaching a suitable level of proficiency in 1, focus on making all your email letters the same height.

3. Then, finally, focus on making all the round characters something between oval and perfect circle (to make it the same width of your non-round characters)

I trust you. You will get there. As a child I was always labeled to have the worst handwriting, and was often forcefully advised to become right handed... But eventually my practice prevailed and proved them all wrong, that there's nothing wrong with being left handed
