Feeling guilty

I’m 7 weeks now and struggling badly with nausea and exhaustion. I have a demanding job and that is basically all I have the energy for. I’m generally a very present person for my friends and commitments and I feel so guilty for not being able to be that way anymore. I’m part of a non profit organization and not pulling my weight but no one knows my news so I just feel so guilty for having excuses for not being able to do things but I barely feel like I’m surviving.

Can anyone else relate and should I tell someone in this group so that they understand?
