I haven't been in a relationship in 2 1\2 years. Not because of social anxiety (which I don't have much of). But because my anxiety has took away my confidence in being a suitable mate for anybody. Anxiety has really affected my self-esteem. I've been working on a lot of self-improvement. I've been exercising, eating right, and taking vitamins and fish oil which I believe helps. I've also switched from whiskey to wine and lowered my alcohol intake. But I still have a long way to go in terms of making this thing manageable.
As time goes on I've learned to accept my anxiety instead of trying to battle it with drugs and alcohol. Drugs and drink give you a buzz. That's all they should be used for. Self-medicating for psychiatric issues is only going to mask the problem. As cliche as that sounds its very true. I don't know the extent of your drinking but read up on how alcohol effects anxiety levels. I could tell you all about it but reading the articles themselves is pretty...shall I say sobering?
Vitamin supplement sure don't hurt. However, just so you know, the only vitamin supplements that have ANY proof to actually make you healthier are...
St. John's Wort - (more effective than most conventional antidepressants for depression and anxiety)
Valarian Root - (This has been nicknamed "The natrual benzo." This has also been proven to be more effective than most conventional anxiolytics. However, Benzodiazepines are still considered to be vastly superior. With that being said, Valerian Root has proven to be more powerful than SSRI's, Tricyclics, and Antipsychotics for anxiety)
L-Tyrosine - (Proven to be affective for depression. Studies have shown it may also be used to treat ADHD, as L-Tyrosine causes an increase in attention and focus)
Vitamin D - (I believe I remember reading that it is the only vitamin supplement that's benefits outweigh the risks. It is also the only vitamin supplement to have hard evedence to be a promoter of good health and promote a good sense of well-being)
Omega-3 - (Omega 3 is a lipid (a lipid is a fat) that's considered a "good" cholesterol. Omega-3 has been proven to promote the regeneration of brain tissue)
Fish Oil - (Fish Oil contains big amounts of Omega-3, but also contains the possibly harmful Omega-6. Fish oil is definitely helpful, but taking pure Omega-3 supplements (these are called "EHG" supplements) has shown to actually be healthier. However it's still disputed whether or not this is the case.)
Those are the only ones I remember the descriptions for. The rest are...
Cinnamon Extract
Folic Acid
Cranberry Extract
Green Tea (Or Green Tea extract)
Probiotics for the digestive system (all other probiotics were shown to actually cause more damage than good)
