there’s so much anxiety in my head today

TW I’m feeling really bad about myself today. I feel like a fraud and a liar. I’ve been unable to enjoy my time with my girlfriend because I’m bombarded with my thoughts. I’ve been asking for reassurance from so many people and nothing is helping. Nothing makes me feel better anymore and I’m worried that this is just how it’s going to be for forever. I miss when I could just be happy and not overthink so much. I miss being able to get through my days without this crippling anxiety. I’m worried there’s going to be a day where I realize I have no fight left in me

My allergies are probably to blame mostly but I keep feeling like I got brain fog and it’s hard to concentrate. My ocd says what if you loose control and don’t know where your at and can’t concentrate and complete and task. I feel like I got alot going on trying my side gigs etc and working. Not feeling the best today.

I’ve been feeling a little bit better these past few days but today it’s been very stressful for me having a lot of hard thoughts and unable to release tension mentally giving me a headache and feelings of panic. Having a hard time connecting with reality. Any ideas or suggestions on how to grab myself and release tension?
