Welcome to our forums. It's great you have made the step of reaching out here. Many find that initial step very difficult, so you are doing great.
As Sophie M has indicated there are many of us here who have anxiety and at times struggled with it. Sophie has also given you some great places to reach out to.
You sound quite young, in comparison I'm at the other end of the age gauge.
Being here has helped me a lot over time. The things I've learnt are - how I'm not alone, how welcoming everyone is, useful tips about managing and coping with anxiety, what works for some and what doesn't work for others.
It was many decades before I was diagnosed with anxiety. What a relief to know that the oddity of my life was not that there was anything wrong with me, it was all to do with how my body was wired and how it responded to certain situations. Wow - did that explain a lot. Why I wanted - to cancel on social outings, run out of packed rooms, not get out of bed in the morning, drink alcohol to dull my emotions and feelings, I perspired for no good reason. These things still happen, but it's no longer frightening and I'm able to reduce all these sensations by using controlled breathing, by acknowledging what's happening, by accepting what's happening. That being anxiety is okay - that there's no reason to be frightened of anxiety. Being frightened of it only makes my anxiety worse. It's taken me years to get to this point and there are days that my management techniques don't work, but these days are infrequent now.
You are young and have your life ahead of you. Living with anxiety is achievable. I worked for 50 years, studied at uni part time while working full time, travelled to beautiful places, am married with a wonderful husband (of almost 40 years)) The road has been rocky but it's been fun, interesting and full of joy. On reflection I think anxiety has motivated me to do things.
Hope some of this helps you Amy_b
