Should I quite?

Hi. I’m new to trading. Been learning for 1 year now, just started my first trade last Monday. Currently in profit, deposited 15$, now it’s at 43$. Thought it went to 70$+, just lost 30. It’s causing me a lot of stress, like a lot. and yes I have a bad emotional control, I’m quite sensitive. I’m still in college so I don’t know if I can do this. That is why I’m posting this, need someone’s opinion. Some tips may help too. Thanks!
