I have no one to talk to!!!

I have no one to talk to about one of my problem. I can't ask anyone for their advice. I really don't know what to do? I usally ask my bbf she a older sister i never had about men problems. I can't even tell her the problem. She knows about my suitation. I keep hearing can't fix something get rid of it.  Dont know what to do? These days I haven't been feeling well. I thought it was the heat bothering me. I had no choice but go to the doctor today to find out why I'm having these headaches. He took my pressure. My pressure is really high. He ask me what have I been doing. I told him I been working alot and I'm not sleep well. I told him im thinking alot about my problems.  He said i need to relax and get more sleep. Stop thinking so much. He said if it gets any higher he going to give me medicine. I got try to relax more. What should I do....
