I had a lot of anxiety in my early 20's, so I can understand somewhat how you feel.
The good news is that this will not last forever! It usually does help to talk to a therapist, because you can confide things to them that you would not confide to family/friends. If the therapist/doctor you are seeing feels that you will benefit from medicine/antidepressants, it may take awhile to find the right one for your chemical makeup, but when you do, it can make a world of difference. Once again, most likely a temporary condition that will pass in time. Here's hoping you feel better soon.
