It's been a long time since I started hinting to my family that I'm interested in girls,tho I never tried coming out, but I was caught talking to my girlfriend. My mom took my phone and forced me to break up with my gf. Of course I did. I cried and beg my mom to let me talk to my gf one more time but she was cold. The first time I saw her like that. I wasn't able to do anything but I still really love her

What does the rest of your family say about that? Are they reacting the same way as your mom? If not, I would recommend you to ask them to talk to her (your father would be the best option in my opinion) and see if she can try at least to understand that you truly love this girl and that it's really unfair what she's doing. You have the same right as her to love whoever/whatever you want
However, if they are reacting the same way as your mom then I think that if you show how much you're hurt by their unsupportive attitude and the fact that you can't talk to your gf anymore, they'll eventually try to understand you and with time even support you. That may take some time, it's really difficult to change someone's point of view(especially if influenced by religious beliefs and even more if it's your parents) but little by little at some point, someone is going to rethink everything through.
If that doesn't happen, then just distance yourself, if they can't love as who you are and want to love a fake idealized and unhappy daughter then they are not good parents and do not deserve your love. It's harsh but, in my opinion, that's what they should get. Distancing yourself doesn't mean being irrespectful towards them, they would just get even angrier, but just talk to them as if they were your teachers: polite but not too friendly. They will notice it (I hope...) and (I hope...) will regret their behaviour
About your gf, can't you see her at school/university? Explain her everything and she will understand and give you time to solve this problem (oc there you can act with her as a gf)
I hope this will help you, and remember you should prioritize your happiness over theirs.

None of my family supports me and one of my problems is it's quarantine and we go to different school,her parents accepts our relationship. And up to this day, I still haven't talked to her

Can't you send her an email or something? Your parents can't prohibit you from using your computer if you're in quarantine.
In any cases, you should try to distance yourself, they need to understand your pain.
Good luck, girl <3

Hi !

Is there a LGBT support club or group in your place ?

The way to deal with that varies largely among places and context, and the background of your mom.
You should ask them for guidance.

Anyway, keep in mind that even for the most open minded parents, it takes time to process that their child is gay and they might not have grand children.

So while they check your phone, you can just create a new email address and online identity. Sites like tutanota don't require previous email, phone nr, or physical address for registration.

And you can use Matrix, Discord, or IRC for IM in browser, in a private tab.

You can also hide apps on a smartphone or a PC.

I also don't know how old you are.
If you can get some independence from your parents, like by getting a flat to go to uni, you could do that.

or use the drrr chat if she agrees.

it's convenient

So Drrr has turned into lgbt fetish smh
