Hi ac
That's why you shouldn't read anything online - its not helping you recover. When you're suffering anxiety you will have anxious and negative thoughts, and you will be drawn to negative comments online too. Just don't read them. If you want to recover then you have to make a start somewhere ..... and that can start by not searching online for symptoms that you don't have.
Your anxiety / fear won't let you at the moment ....... but if you start making changes, then everything else will start to follow. Making changes won't make a difference today or tomorrow, but you have to keep persevering and it will happen.
I know how believable those fears are - I had them, many of them, and know how strong they are. I truly believed there was something wrong with me, I'd constantly look for an answer, felt comfort in some stories and was scared by others. New thoughts and fears would emerge and each new one felt ten times worse than the previous one. But I was doing this to myself even though I didn't realise at the time - I was keeping that anxiety fresh and alive by being afraid of anxiety's side effects ....... thoughts and beliefs. They were so strong I never thought I'd be free of them, and I never believed it was just anxiety that was the cause of all my problems. I could never believe that my thoughts would never stop causing me anxiety, because I only had to think of them and I'd get a whoosh of anxiety fire through my body, reducing me to tears. It was like my brain HAD to think of the worst possible thought or scenario, as if to test myself if I still had anxiety. But I had to learn to let those thoughts be there, had to let that anxiety shoot through me and I had to learn not to react to it. My god it was hard - my body naturally wanted to go on the defence, but I had to do the opposite of what it wanted to do ....... and that was let it all happen, let the thoughts rage, let that anxiety come time after time ....... and just relax towards it and carry on. Your body and mind relearns that it is not in danger, and as the anxiety lessens so do those anxious thoughts and all those health anxiety thoughts too.
Stress and anxiety won't harm you - its your body's natural defence system and is actually there to protect you from danger. Its been a human feeling for 1000's and 1000's of years that has helped many a man from probably fleeing a woolly mammoth, to sailing the seven seas in raging storms and helping when in battle. Having stress (adrenaline) never killed them, but it prepared the body for fight or flight. You're having the same stress feelings they had which has turned in anxiety - neither of these will harm you.
Anxiety might come back for a number of reasons. Change of meds brand is one. Many people notice an increase in anxiety when their brand is different - check yours. Increasing meds causes anxiety to be heightened and yes it can last 7 weeks ..... especially if you're 'fighting' it.
This is why I stress about learning about anxiety, understanding about it and how to help yourself because that skill will never, ever leave you and one that you can always fall back on.
I used to say life was unfair too, and felt robbed of 16 years of my life. I was one angry person. But strangely having gone all through that and out the other side I feel somewhat grateful for the experience now because its as if a light was switched on as I learnt more and more about anxiety. Its now not the monster it once seemed ......... and life is more than sweet now.
You will get better xx
