Tired of being depressed. Need advice/help.

I'm 15. I'm a sophomore in high school. I have ADD (which means I have a hard time focusing) , generalized anxiety disorder, and mood disorder (I have symptoms of bipolar disorder and depression). I've had ADD since I was 8 and have been taking vyvance 60mg ever since. I've always had anxiety and from what I can remember my depression started when I was 10 because I had friends that bullied me all through elementary school and middle school, and I struggled with my weight and still do today and was very insecure about myself and still am today. Two years ago I started seeing a therapist once every week and got a psychologist. I was diagnosed with anxiety disorder and mood disorder with symptoms of depression and bipolar disorder. I take Latuda 40mg and vybrid 60mg for all of that. I'm working on overcoming my depression and anxiety and working on trying to control my mood swings. I've tried going out and doing things with people and not staying home 24/7. I've also tired changing my mindset but it's really hard to think positively instead of negatively. I'm just really tired of being depressed and not happy. I'm just always feeling down all the time and sad. I'm not suicidal but I'm just tired of life sometimes and want to give up. I just don't know what to do. I'm tired of feeling this way. Please comment if u have any similar issues or experiences like me and how you overcame it or r working on overcoming it. Also please comment if u have any advice, tips, or suggestions on how to deal with my issues and how to overcome depression and not being happy all the time. Thanks! :)
