Why am I so different and a disgrace just for loving?

There's no no much thing as disgrace in love. You love who you love, and that's ok! People may judge you due to cultural prejudice, stereotypes, their intolerant upbringing... But intolerance is the true disgrace, not love. If you surround yourself with supportive people as much as you can, maybe it will be easier for you to embrace this part of you. Love is something wonderful, whoever you share it with. Those who believe the contrary have no right to make you feel bad because of their own prejudice.
