Kevin, I am going through something similar to this. This is just some of my experience with anxiety. Some days are better than others. Anxiety can be very frustrating. In conjunction with less sleep, it can make you lash out at people close to you (proximity or relationship wise). I have felt much guilt over snapping at my boyfriend, and my mom and dad. I'm glad you are getting help with a psychologist. I have only been able to see a family counselor type, but it still helps to air out some of your concern. They let you know that you aren't losing your mind. =) I think that the lack of sleep and other life stress causes your attacks during playing sports, it makes you more nervous and less aware, so things can seem overwhelming. Maybe it is just me, but I tend to take things I love doing and get so afraid I will have a panic attack during them, that I will have a panic attack. I feel silly when it happens, nevertheless it happens. I hope things get better for you and I hope you figure out how to deal with the anxiety. I'm going to try a somewhat of a self help program to see if I can talk myself through the anxiety. I think that I listen to only myself when having anxiety, which usually makes me more nervous because I always think the worst. I guess that I want to try and see if talking myself through it rationally will make it better. I look at it like a roller coaster ride, if I don't go with the flow I feel panicky and I am resisting the motions and I get scared. So I want to go with the flow and get to know the sensations when I am having anxiety and not resist them and to no think only negative thoughts. I think that it may help me.
You aren't alone and you aren't losing your mind. =) I know it feels that way a lot. Maybe it will help with the girlfriend situation if you talked to her about it and if she understood how you feel and what happens when you go through the anxiety attacks. A lot of my frustration in that department and why I snapped at my boyfriend was because I didn't feel like he understood or even cared about what I was going through. This is just all personal advice and feelings, not professional. Welcome to the forums here, I'm new here too, but no stranger to living with anxiety. I hope you get some good sleep soon, maybe try some meditation and/or natural melatonin? It helps me sleep for the most part. I hope any of this helps you. See you around.
