I have suffered with SEVERE anxiety, believe me, I know exactly how you feel! However, I conquered it, and I'm going to tell you exactly how I did it!
Make a list of everything you don't like in your life (be realistic)
once you've made this list, try and eliminate all the negatives, things that make you feel bad (relationships, people, etc)
Make a list of what you enjoy about life (also be realistic) and try and do these things, or at least make an attempt to.
Surround yourself with POSITIVE people, I can't stress this enough, find somebody you can talk to, talking to someone is the most important thing, especially with anxiety. there's always somebody there who is willing to listen.
Go and see your GP!! I did this, and it helped a lot, I cried, I said everything I needed to say, and I felt better. crying always helps, get it out!
If you need anybody to talk to, inbox me, I'm open minded, and I've been through a lot, I wish Anxiety on nobody, I know exactly how it feels.
