dam, I feel u tho. Let me help (if you can even see this for it's 2 weeks ago). Usually they block sites with your IP address, so even with an alt account, it is quite useless on the same PC. To by-pass this, use free web proxies or VPN extensions, but the most popular ones are usually blocked too. Again use lesser know proxies but good proxies such as CoProxy or its extension form CoProxy VPN (that's what I am using rn). To prevent your parents finding out, use Incognito Mode with the proxies and with extensions, remove them once your done. I hope you find a better way but this is what I gathered for now.
