I need to get this out of my chest

Lately I feel like my life is going down. First I lost the person who I loved the most because I got a pregnancy scared. Second my best guy friend has a gf but he is mentally cheating her with me. Third one of my friends always gets mad at me for no reason. Fourth I am stressed because of my college applications. Now I am sitting in my room crying thinking about when and where did this sadness come from.

Please I really need kind words right now. Let me know which one do you guys want to know about the most.

Update: Last night I texted my guy friend and I told him how I've felt he told me he got jealous because I was texting someone else. But then I asked him if he was actually happy in his relationship, he didn't respond quickly but at the end he said yeah and I said to him you took that long to answer that he got said "I am. I want your body" that's when I told him you you know what its better off not to talk to each other
