I'm feeling depressed and anxious again and I don't want to tell anyone
I am sorry to hear you have been feeling like this. Why do you want to keep your depression a secret from everyone?
I don't want to tell anyone because I think I will be a disgrace to my family
Feeling like a disgrace is not that encouraging, but they might understand. Be upfront with them, they could help you get some therapy to sort out your feelings. Staying away from everyone just exacerbates the depression and causes more anxiety for you.
Nah, I'm going to act tough.
If you want to feel good you should talk to someone. Getting help can only make you a better person.
