Plz tell me a solution to restrict others(in my network) from logging into my pc using the command: ssh my-ip-address

They need to type in your password to successfully log in. If they know the password, change it (or add their IPs to your /etc/hosts.deny

or just kill the ssh server..

Unless you have given out our password to anyone - you don't have to worry about them logging into your server via SSH using your credentials.

If you don't want anyone to log into your server via SSH - you can ask your server admin to disable the SSH service completely per se.

Put SSH on some port other than the default, to minimize brute force attacks.

You can also create or get some crontab script that parses the /var/log/secure* files for repeated break-in attempts and adding those IP's to your /etc/hosts.deny file.

Or get yourself a Router device and use NAT port forwarding to hide your SSH port by means of redirection.

Must be a tough neighbourhood if you are attacked by users from your own network. Maybe even change your password every few days.

You should also use the option in the sshd config to disable (remote) root login anyway.

You may use public key and private key to login your pc instead of using password , so other people can not login with brute force attack.
Also, you may install the software like fail2ban to block malicious user.
