Lonely and Bored/Please Read

I not trying to throw a pity party anything but I’m bored and lonely. I know it’s makes me have emotional up and downs and it’s getting to the point where it’s a down. I have only three friends who I actually talk to; the reason why I don’t have more is because if I can’t be myself around you then we can’t be close. So I’m out for summer and I am completely bored: I can’t drive alone legally, it hasn’t stopped raining in almost two week and the forecast shows no sunny days. All I do is stay in my room and usually watch Netflix. I have nothing to do; I’ve tried writing but my mind has no new ideas (I’m pretty good at writing) and I’m not artistic and my family for the most part is either busy or bothersome. I’m just stuck I was looking for a way to achieve a happy state of mind but it’s difficult right now with the circumstances. I’m 15 and I’m just stuck. What should I do?
