HI Cognitive Behavioral Therapy Training - thinking of dropping out

So I have obtained a role as a HI CBT trainee. I was a Mental Health Social Worker for over 5 years previously and found myself burnt out towards the end with unrealistic workloads. I thought this opportunity would be great as a career change and was the only thing I could find offering a similar pay scale etc. I have started the course and initially finding suitable clients has been a challenge. I have eventually built up my clients (although still behind my peers) and started sessions (at around session 3) with them. However the course is moving at a really faced pace. I have a young child about to start school and a self employed husband who is trying to build his business. In the first week of starting the course we had a car accident and then my car broke down and it all just felt a little too much, I became teary and unsure of myself. As the next week came round, we had moved on to the next bit of learning at University and I was completely overwhelmed. I struggled to find additional time to prep for my client sessions, prep for supervision as well as do extra reading/learning and the thought of adding in time for assignments caused me to spiral into full blown anxiety. I have been signed off sick and been offered additional support to return such as reduced caseload for a while and extensions on deadlines, however I am questioning if this is do-able if I am struggling with time. I'm only 2 months into the course but considering if it is best to just walk away now.
