I have to start out by saying "good for you man for starting this thread". It shows you are aware something isnt right but you have the courage to ask for help and suggestions. You are on the right path already.
I can relate to how your feeling and will add my 2cents. Im in my early 30's, but most of my pre-teen, all the way up till still now ive dealt with depression, anxiety, confidence problems, etc.
I always had problems talking to girls as far back as i can remember. i couldnt even look them or anyone for that matter in the eyes when talking to them.
I started working out when i was around 15 and got hooked on it. i thought if i just build a great body it would make up for my insecurity issues/confidence. And i can say that it did help some when it came to getting girls, but that only goes so far. Woman are most attracted to guys that are confident(not cocky), good personality, and driven in life/work. And of course haveing a good physique doesnt hurt!
So, later on when i got to college i was still struggling with the same issues. I ended up meeting a girl who was interested in me and pursued me which i liked because i was so damn shy. Well thats when i was introduced to partying and drugs(mostly xtc). I got hooked so fast because this drug basically cured all of my issues, but only when i was on them which was always at night out at the clubs or afterparties. during the day i was back to my old self.
Then at 27 years old, i was diagnosed with sleep apnea. I wasnt overweight by any means, which is why doctors never considered i could have it even after i told them the symptoms i had.I was always told that it was my fault that i was tired all the time even though i would sleep the amount of hours i was supposed to. it got to the point after much research that i demanded a sleep test. The test revealed i had 260 apneas(body waking itself out of sleep cycles) in the 6 hour sleep study. Because the back of my tongue was larger than normal, and i still had my tonsils, plus a deviated septum, i was sleep deprived for atleast 15 years. This first off explained why i always fell asleep in every class(except gym) all through my school years.
It also, i believe, was the root to why i had all the issues ive mentioned. Im not saying you have sleep apnea, but its very important to be pro-active when it comes to your health and well being and not to rely fully on doctors.
When it comes to the healthcare in this country i am 50/50. There are so many proven, effective treatments for so many different health issues that doctors have no clue about because most of them work better then the treatments/drugs your doctor only knows about. But this i feel is the result of what students going through medical school dont learn about, because there is more money to be made with treatments that last longer. For example, and this is personal experience, i was put on prozac(one of the several diff. depression/anxiety meds ive been prescribed over the years) to treat my mood issues and it made me feel nothing. i was like a zombie. And then come to find out if you stop taking it you go through withdrawls. Not to mention the long term damage that it can have on your brain itself.
Im getting a but long winded here so ill sum it up. like others have already mentioned, start with the basics. Eat right, workout in moderation, make sure you get enough sleep at night and try to get on a schedule.
Also with vitamins/drugs, start with what is natural and proven to work(fish oils, coq10, melatonin, 5-htp etc) but again in moderation.
Instead of talking to a therapist, i would recommend reading books that are about the issues you are dealing with. Especially books written by doctors who beleive in alternative therapies, because to maker an appointment with these type of doctors, most cant afford it because insurance wont cover(ex.anti-aging, holistic, neuro therapy through the reading of brainwaves and treaments to help fix any issues, etc)it.
Work on yourself in all ways, find an occupation you really enjoy and focus at being the best you can be at it, socialize with your close friends, and dont worry so much about finding a girl. More than likely, you will find what your looking for when your not even looking for it! It can get better. If you want to private message me with any questions please do. I still struggle with issues from time to time, but as a result have become very interested and love studying about the many different types of therapies, supplemts, and drugs used around the world. You would be surprised how many treatments are suppressed or illegal in this country that are far superior to what doctors here in the states have no clue about!
