Can anyone suggest me something according to my situation please?

Soo its been more then an year since am dating, but since very long time my mental health hasn't been really good, i had fake friends, and because of them i just probably lost all my friends, i have started being very distant with my best friend as well, and am dating rn, but i am just not happy in life, and i feel like its affecting my relationship, my partner isn't a bad person at all, she is trying her best to make me happy but i feel like i just can't be happy anymore, its been years probably now since last i was really happy, and i think it was when my sister was getting married and my other sister got into a really good job, i feel really distant from even my own family now, it seems like everyone just forgot about me or dosent care, can anyone please suggest me something before i do something stupid or something I don't know whats even happening anymore
