I’m ASD 1 and so is my 16 year old. Best advice I can give you for now is spend time learning to be kind to yourself. It’ll make everything else easier to manage. Really focus on self compassion. Often times mindfulness meditation is an excellent way to get there.

You need a job that feels like solving puzzles and requires little human interaction. Here's a list from indeed:

The other alternative is to just get whatever job you can and see how you like it, there's no punishment to quitting, you'll just be where you are now.

First step would be to get some sort of professional help, other than just taking medications. Medications alone will only get you so far.

Do you have access to a Regional Center or something similar? I used to work as a coach for young adults with disabilities (I am autistic myself, level 1) and we would have volunteering opportunities along with formal job opportunities for our clients. Contact your case worker so they can guide you to the right program

As much as I hate to say this, money makes everything easier. It would make sense to get a side hustle or two. Or volunteer somewhere. Develop job skills.

Figure out what kind of job you wanna do, try diffrent things. Don't be afriad to fail at stuff, because it teaches you what you are not good it. I always remind myself it's only a failure if you don't learn anything from it. Even if the lesson you learned is to never have a customer facing job ever again.

As for money, you could sign up for crowdtap. That is a site that is for ages 13+ and you get points for answering surveys. For every 1,000 points it's $5 in a giftcard, $30 maximum for some cards. Within a month of using it everyday, I got $50 max. It's the most legit site out of all the others I tried.

Upsides: there are lots of giftcard to choose from (Amazon, Walmart, Sephora, etc.)

Downsides: some surveys ask for very basic information about yourself, you have to have a cellphone number for verification (maybe you could get a VOIP to get around this)

If you are uncomfortable doing surveys, you could create art irl or write things in exchange for money. Lots of people in the art community have commissions. There's PayPal and Kofi for online payments, PayPal also have their own MasterCard debit cards that you can sign up for to use on sites that don't take PayPal directly and in stores.

You are likely not going to receive good advice on job opportunities because people here don't know where you live (and you shouldn't tell).

As for fun, a cheap, old computer can go a long way if you're capable of enjoying old games. Depending on your social circle, there are also a lot of fun, afforable tabletop games.

Regardless, if you have good reason to think you're absolutely stuck in your studies, it's possible that continuing high school could actually be a bad idea and you should be looking for alternatives - but since it sounds like you're a minor, this is something you should discuss with your parents. You might have more luck with alternative educational paths, or you may have too much difficulty to learn while you're struggling with depression but be able to graduate after a couple years, or you might have an easier time to learn a career on the workplace itself. Just keep in mind that it's extremely difficult to get started in some industries without an official title.
