Anxiety disorder subconscious mind?

for the past 7 months i feel anxious like im worried about something in my subconscious but it wont come into my conscious. its a really uneasy feeling that doesnt let me relax because im always on edge about something but i dont know what it is. my symptoms include muslce twitching, muscles are tense especially in mouth, bad dreams, insomnia and just an overall anxious feeling. what am i suffering from and how can i stop it? can it easily be cured?
