Life keeps taking from me. Help? Really depressed..?

Hi so I am a happy 17 year old girl, but recently my life has just gone completely downhill. First, I had my first real heartbreak. First love, everything. Now he's gone. But that's just the start of my troubles. Next he started acting like a jerk out of nowhere. Was telling me to kill myself (never ever would no worries). So now I've lost our friendship too. Then I was going to go to las vegas (my happy place idk why dont ask) but Ceasars overbooked and also overbooked our brittany spears tickets. THEN one of my BEST friends in the whole wide world DIED. Motorcycle accident. I am SO crushed. FIRST I had to deal with losing my love and then HER. I just can't take it. She was going to propose to her girlfriend and she wanted kids. She was only 31!!!! She was my adult friend who knew ME and we had fun as if she was my age. I just don't know what to do anymore. Nothing good has happened to me. I throw myself into stuff like hobbies and friends. Sometimes it helps but by the end of the day I'm broken. It's to the point where every little disappointing thing makes me cry like how my parents will get mad that I got locked out of the house. Hearing them so mad makes me go to my room and cry. I know I'm loved but I feel so hated and lonely. Normally my ex would have been my anchor to me during my first death, but he's not here for me. My friends are, but it's just not enough. I can't afford therapy and I've tried self therapy EVERYTHING. Please help.
