18 y/o with 5k in cash

Hello, I’m just coming here to ask what I should do with my money at this point, or if my current situation is fine.

I make some money currently (~500 a month), but will be getting employed either this summer or start of the next school year.

I currently have ~$5100:
$1130 in a long-term stock portfolio (+$25 weekly)
$550 in a short-term stock portfolio (more speculative)
$1000 in a HYSA (3.5% APY)
$2350 in my checking account

I mostly feel like I have a little too much in my checking account, but I’m a little nervous to invest more into my long-term portfolio in case of a crash, and I just feel like the HYSA has minimal upside, even if I put another $1000 in that’s only $70 a year.
