Help me get a grip

I’ve had anxiety and depression since 9th grade and I am currently in 11th. I would get bouts of anxiety and depression throughout 9th and 10th but I was mostly depressed and I worked really hard to fight it and better myself. Now I’m having a fight with anxiety I keep losing. Lately it’s become so bad I’m having trouble telling the difference between reality and what’s in my head. I feel like my brain is constantly on fire with worrying thoughts about my love life and my school work. I have really intrusive self deprecating thoughts. I have and extremely supportive boyfriend who is very reassuring and kind and patient but I wanna get better for myself but also for him. I don’t want my anxiety to keep affecting my relationship and my health. Does anyone have tips on how to help control and calm anxiety.
