Hello there, i'm new to this site i registered today but i saw your topic and i myself have some anxiety issues i thought i would try and help.
i'm a 20 year old guy who never had any issues whatsoever, in the past i would not care about anything and do crazy stuff as a rebelious act just like every youngster would do, in the past 2-3 weeks i developed anxiety due to a scary drug related issue, i had and still have anxiety that made me feel pain in my body parts that were not explained, headaches, pain in the abdomen, numbness in the leg, all sort of problems. i was so mad and angry at the fact that i'm so unlucky and this anxiety or panic attack that had suddenly hit me had never did before, until today i was convinced that my old life was better and that i was smart before than i was now, and tha i, godforbidd, have developed some kind of an illness that will never be cured. i always thought that anxiety would affect the way i study and that i have exams in a week from now so you might feel the stress i'm in, after a relief from some of the fellows around here especially gillian20097 and my good friends and family, i tried to relax and let go of the stress and anxiety, and i had to go to college earlier and thought it would affect the way i would concentrate in the lecture so you can understand the pressure here, when i arrived at college i let go of the fear and actually concentrated more on my study, so if anything this stress has affected it me it was in a good way, and the reason it was because i learned inside the class to use the pressure to my side and fight, beleive me i have a lot of pressure going on but the hell with out, let go of your fear, let go of the worries and learn to accept yourself before expecting others to accept you, not having a boyfriend/girlfriend or not having sex is not that of an issue, actually if you thought about it relationships brings nothing but worries and hatred, unless it's marriage we're talking about, anyways that's not the point, cope with your self and accept yourself becasue no one is there to judge you, change is rare but when it happens it can be difficult, nontheless don't be afraid of changing, it's always for the best, i myself have trouble breathing sometime and have sensitivity to light and can't concentrate sometimes which made me worry of getting bad grades, but that feeling fades after you cope with it and try to accept it, don't worry too much and learn to relax, and trust me on this, no one can ever help you but yourself, not your friends or relatives, although family can be a great way to go back to, we all have time that makes us independent and confident, have faith and god bless.
BTW i'm sorry for this long paragraph haha, it's just that i had these same symptoms and got so into it, i wish you all the best ion the future and hope you find your path to happiness as i'm sure you will.
