Well for most people it always helps to have someone to talk to about it. There are hundreds of thousands people experiencing things just like you. Based on what you have said though i would suggest you see a doctor some of those may be serious or may not who knows unless you get it checked out. And as far as the boyfriend girlfriend thing goes, i wouldn't worry about it having a boyfriend/girlfriend is overrated anyway unless you really really like someone.

If you need someone to talk to you can always pm me and i'll be more then happy to just talk about anything. Best of luck
