I'm afraid your only way that I know of is to manually re-add all your friends through the community search

And get rid of your other "friend" who deleted all of them.

i cant add any friend

i cant add any friend

that's becasue you currently have a limited steam account, until you get a full account by spending $5 USD in the store or by wallet funds parts of the community wont be avalible to you

Actually you can use this site that can actually show your friend history and more https://www.steamid.co.uk/profile/76561198060531699

@Greenfields thanks for the mention.

It works via steamid.co.uk providing the site has loaded your friends list previously. Every time the profile loads it will grow the history (If there are different friends). This isn’t very accurate but it seems to work well for most people and currently the only way I think this can be done?

JUST... Add them back the normal way? Idk

I think it’s the difficulty in remembering people’s gamers names as profile pictures, names change overtime, I have a copy of my friends list personally but if I lost them without it, I don’t think I could add 1/4 of the people back on.
If you can find friends, it may be worth crawling through the profile as you could have friends in common? – On Steamid.co.uk I did add in “mutual friends” on the friends table which also may be of use in speeding up your search (Not trying to plaster the site but I think its genuinely of use in scenarios like this)?

The C:\Program Files (x86)\Steam\userdata\<Steam3ID>\config\ help me to find my friend back.
