"1. I'm a homebody so it does not affect me much when this lock-down will end. " Homebody is a very unusual word that no-one really uses. A better word is "recluse". In this context it also sounds better to use the present tense for the lockdown ending. So: "I'm a recluse so it doesn't affect me much when this lockdown ends" "2. I have experienced to stay home for a year and my slippery was covered in dust." You wouldn't say "I have experienced". It's better to say "I once stayed at home for a year". I assume you mean "slippers" not "slippery". Slippers is plural, so you say "were covered" not "was covered". So: "2. I once stayed at home for a year, and my slippers were covered in dust".

Thank you

"Homebody" is American English, which explains why @HenryTilbury thought it was 'very unusual'. It's fine to use this word for a US or Canadian audience. In British English, we might say something like 'I'm the stay-at-home type'. This means that you're happy to be at home and you prefer it going out. A recluse is different: a recluse is someone who avoids human contact.
