Not sure what to do anymore

So long story short I’ve been struggling with anxiety lately. I’ve always had it but just the past two weeks-month have been very difficult for me. It’s to the point where I can hardly breathe. I know it’s all mental and that i can but i feel like im not breathing to my full potential and my mouth gets SO dry i can’t even swallow. My heart has palpitations during this time but i don’t know if it’s due to that because i typically have palpitations every day for the past few years.

Also, my memory is crap. I can’t remember anything. I forgot the name of the place i was starting my job at & a lot of other things but I’m too embarrassed to talk about that. Most nights i dont fall asleep until 2 am and then when i wake up in morning I’m usually dripping in sweat. And apparently I’ve been sleep walking and doing things i don’t remember (for example , i apparently got up in the middle of the night and closed the bedroom door and locked it the other night)My mind feels like it’s running constantly with so many different things and i can’t seem to catch a break.

I recently got a job and was suppose to start today but i literally let my anxiety get the best of me. I’ve been thinking about the job all weekend and was back and forth on whether i wanted to do it. It got down to the last minute and i couldn’t get myself to go.i did all the online training and filled out all the documents and was ready to go.. 😫 I can’t help but cry all day because i don’t know why i am like this. I just feel like things aren’t getting better for me. I hate reaching out to doctors because i feel like no one is going to help me or understand.

I would talk to my husband but he doesn’t really understand what I’m going through. He thinks it’s just me being emotional but i feel like it’s much more than that. I just want him to understand and be there for me. I really don’t want sympathy but i would like him there when i really feel helpless.

Any help/recommendations/guidance is needed and welcomed .

Thank you
