Life in a few words...I guess

Hi, I am new here and I am not sure what I am looking for but here's my story.

I have not been officially diagnosed with anxiety and I don't know how that really works. I am not good at asking for help. It all started 3 years ago when my brother started getting in trouble with the law. I remember I was in class when I got a phone call from the court telling me my brother has been arrested and I need to come for the bail hearing. He was constantly going in and out and as the older sister and the only guardian I had to make multiple trips to the court and detention centre. There was a lot of begging people to help me bail my brother out, getting blamed for my brother's actions by my father, waking up in the middle of the night by a phone call telling me my brother was in a car accident, taking care of my younger sibling while working, going to university and dealing with family drama. I went through it all and I was a mess. I didn't turn to drugs or alcohol but i was an emotional reck. Crying in the middle of the night, at work, at school and just going through the emotions just to survive. I stopped feeling happiness. I couldn't find joy in anything I knew I had to get my degree and somehow I managed to do it but I lost all motivation to strive for a good career. I just wanted a job to pay my bills and I had it. Someone told me recently I have no amabitions and even though it hurt I know it's the truth.
