Giving up 💔

So ever since December 2017, things have been continuously getting worse. (I say December because my best friend moved) my boyfriend broke up with me and I’ve just been having a lot of meaningless sex after that. All I do is fight with my friends. It’s really affected my confidence and self esteem. I never feel happy anymore. I feel like I’m always angry or crying. I got evaluated just a week ago to see if I had a mental disability. They didn’t give me a diagnosis. Idk how. I have had suicidal thoughts at the most worst times. I’m giving up and I have no hope for anything anymore.. what can I do? 😕
