I am a 30yo F, who has worked in the consulting industry for a while. In the midst of the pandemic, I was hired by my dream firm and have been working there for a year-ish. 

However, my anxiety has been creeping up for several reasons:

1) workload is awful (most days, I sleep for only 4 hours) and deadlines are too tight
2) I had a medical issue which left me unable to use both my hands for 2 mths, and I have not had time to process that
3) I have imposter syndrome as well, thinking I don’t belong 

Recently, I just got pushed for a promotion but i feel something in me has had enough.

I cannot seem to push anymore, and my anxiety in terms of breathlessness, inability to soldier on, near panic attacks is unmanageable.

After a lot of reflection and conversations w ppl whom I trust and love, I know I have to reject the promotion and quit this company for my sanity.

I just feel sad that on such a career high, everything looks good on paper but I am in utter agony and misery.

Can anyone relate/ give advice/ assure me that things will be okay?

Thank you so much
