Bad Things Keep Happening...

Someone help me give me advice. I’m 16. This past week has been horrible to say the least. My marks aren’t doing to good. I failed my driving test today. After working so hard I failed over something so stupid. Yesterday I did my life guard swim test and we have to do it under 9.10 minutes and I went over by 50 seconds and failed. Now I have to do it again tomorrow and I’m so scared. I’m getting more panic attacks and I feel like my life is falling apart. I know this is gonna sound stupid but I feel like more and more bad things r gonna happen. Like my bf and I have sex so now I’m worried that I might end up pregnant (I’m on BC) cause why not? So many bad things keep happening. I’ve been crying so much I’m so nervous for tomorrow. I can’t fail again. I don’t know how to calm down my anxiety just keeps getting worse. I’m sorry this is all over the place and I didn’t know where to post I’m just loosing it and need some advice.😭😭
