Hi and welcome Priiiysa!
It sounds as though you are under a lot of stress at the moment.
As an essential worker is your job stressful, especially in these times with covid?
How much does your autoimmune illness affect you? With no supportive family nearby and the financial worries about treatment no wonder you are feeling so stressed.
Do you have any support from friends or colleagues at work?
I also think if you have a GP you feel able to talk to, that might be a help, or is there someone you can confide in about how you are feeling such as a family member even though they're not nearby?
Are you in an area affected by lockdown? These times are frightening and strange and stressful already without the added health problems and financial worries you have.
No wonder you are feeling weepy and snappy at work! It sounds like wanting to stay under the doona is very understandable!
If you'd like to share more here people will do their best to support you. We're happy to listen!
Sometimes just getting it all off your chest to others is a good first step!
How do you feel about a chat with a GP or friend or sharing a bit more here?
We are here to help if we can. Maybe you can tell us a bit more about yourself and what's been going on recently to make you feel overwhelmed?
Only supportive people here! Happy to hear more if you would like?
