Hey, of course I don't know your financial capabilities and the height of your allowance but I encourage you to not give up on your intention to learn bass guitar.
I don't know where you're located and what possibilities you have to find used instruments but here in Germany you can find used bass guitars on a portal called "Kleinanzeigen" (the German equivalent to Craigslist I think) for very little money or for free. Just keep looking.
Also on our big instrument online shop "thomann.de" you find beginner bass guitars for less than 100 €. I am sure you find similarly cheap bass guitars where you live.
Long story short: Don't give up learning an instrument and have the courage to ask people around you to support you.
