Definitely go see your GP, there's no shame in medicating because you are sick.
I have a couple of techniques that can be helpful, but first thing to remember is that you are ill, and that's ok. People get ill sometimes and unfortunately it's just a shitty thing you have to live with for now.
On a practical level, the most successful technique I use involves grounding yourself. When anxiety (and depression) take hold, it's a very internal process that detaches you from reality - so it's very important to bring yourself back to the environment you're in.
If you're feeling particularly anxious or have a panic attack coming on, first thing to do is to remove yourself from wherever you are and change the scenery - that could be going outside, switching to a new room or pulling over and getting out of a car.
Try separating it from yourself, like it's a different body to you that you can't control (because you can't). Say to your anxiety "ok, you have your moment of worry/panic for now, but in a minute I need to get back to work/chores/watching TV so let's just get through this".
Then focus on your breathing, making sure you're breathing out more than you breath in (this could be breathing in for 3 seconds and out for 4, each person is different so find what works for you).
Then we're going to do something pretty lame but it helps, believe me! In your head or out loud, count 5 things you can see and describe them to yourself - e.g. I can see the blue sky but there's a cloud over there, maybe it'll rain which means I don't need to water the garden later. There's a brown park bench, I always think they look nicer in green...
Then 4 things you can touch (e.g. I can feel my jumper, it is soft and warm - I can feel the brick wall, it is rough and cold)
Then 3 things you can hear (e.g. I can hear magpies, god those birds are dicks)
Then 2 things you can smell (e.g. I can smell freshly cut grass, damn that's one of the best things in the word, or I can smell that man's vape cloud and it reminds me a parma violets)
Then 1 thing you can taste (e.g. is that garlic? I swear I haven't had garlic since last week!).
Repeat until your breathing is back to normal and you feel the adrenalin rush has gone :)
I do this every time and rarely get past the hearing stage because it really helps bring you back to reality. This is only a short term fix but having the tools at your disposal kinda train you into realising the anxiety is another illness that you have to treat - not a personal quality (that is really shitty).
And finally, you're not 'normal'. Nobody is 'normal'. Trying to be something that doesn't exist will drive anyone mad!
We all have different things that we're better at, different things that we love and different things that we have to cope with. You have anxiety, it's shit, and you have to find a way to manage it.
I don't know if that's helpful or not, but I know where you're coming from and just wanted to let you know how I cope :)
