Hi, just letting out some steam. Honestly, I have always had anxiety, but past few weeks have grown out of control and even had a few breaking points. I have so far managed to cope with it myself, but now I am seriously having difficulties. Thoughts are running wild and just making every decision hard.  Had a legit breakdown a week ago which kind of troubled my relationship with gf to the point of "maybe we should be apart for a while". Somehow we have managed to pull it back up, but my uncertainity, constant overthinking and other "wonderful" voices are just overwhelming after that. I do acknowledge it and even if I am having anxiety attack I am aware of it. Problem is what follows with it. I am not sure of what to do about it. I try to think it thru, talk to myself about the problems. I don't have suicidal tendencies or anything. I just can't clear my head, constant breathelessness and since life isn't clearing up itself I must deal with my daily problems cause I have responsibility towards people. 
I feel like being tormented by some demon who just loves to see me suffer.

Any ideas what to do? Should I see a doc or perhaps I am able to drag myself thru it?

Normally it doesn't get so bad,but having it is enough to limit possibilities. Now it is decreasing even my strong parts.

Sorry for the unstable and a bit complicated sentences.
