have you ever looked at the "Peers" tab in your torrent client? Notice how every peer has it's own full IP-adress there? Yes, everyone that downloads from your client can also see your IP-adress.
What kind of anonymity was it you thought you had when torrenting? From whom? About what? For how long?
Use a VPN if you want to be a bit more private online. Use Tor Browser if you feel you really really need (but don't torrent over tor). Use disposable email adress providers, or privacy conscious email providers. Use encryption software if you fear people getting to your hardware. But please read up on the subject before complaining.
