Sharing Our Innermost Thoughts

okay, hello! I had this feeling inside me for a very long time, and I would be very honest here. I have lived my life on fear, may it be people or anything in the world. I have fear of being alone, fear of fighting alone. But right at this moment, I am scared to make any decision on my own. now I am so confused about what to do and how to do it. A long time back, my friend met a guy, they both liked each other, let’s name her “A " and her Ex “B”. She was my only friend at the university. basically, she was my best friend. She was the reason I was being good at “B”. slowly we became good friends, I consider him my brother. we had few trips together. but in between the lockdown, A and B broke up. with everything A said to be me, I doubted “B”, Basically she said to me he cheated on her. So I stopped talking to him, thinking A might feel back and she was the only reason I first started talking to B. So before lockdown when everything was good, I had to give my phone to him as I had two and he had an issue with his. And when they broke I was back home, I couldn’t meet him or anyone and ask for it. In between, I tried to contact him, and he said he would give it back. but things got bad, A without talking to me, or discussing with me, she sent her friends to get my phone. and when he didn’t have it, they brought his. now A and me, we not friends any more lots of things happened, and now my friends want my old phone while I have his phone, neither call I tell the truth to my dad nor can I lie. and I do talk to"B” But right now I cant exchange as I am far away. and my dad is pressuring me every single hour. I am so freaking scared and confused. and thinking all of this I cant sleep now can I do anything, I don’t feel good what am I supposed to do?
