Sounds like good fodder for work in therapy. Only you can decide in the end. ((((((((((((((((((((((((((((((((hug))))))))))))))))))))))))))))))))))))))))))))
I guess one thought I have is----if you return full time and it is too much for you would you be able to cut back or get accommodations at work (ADA) that would be effective? And, does the full time include insurance and benefits that would help?
That it is is appealing to you is a positive sign, I think, even if you decide you are not ready. Your mom has a point----and you could turn the job down if you got it and decided you were not ready....
(I always think it is nice to know you have choices...
also, think about how you might feel if you did not get the job...is that OK...)
Talk talk talk....think...list pros and cons....be honest with yourself....
