Feeling anxious trapped and in need of money

[plannedshock]

Will try and be brief. I'm a SE hairdresser on mat leave due to go back in a wk part time.
Used to be full time paying £400+colours a wk to the salon owner, I'm now part time and my "boss" is completely having me over with re:to rent. By the time I've paid him and childcare I will be lucky to pay anything into my mortgage (of any noticeable amount).
I should just go to another salon but I want to have another baby soonish clients will be pissed if I move them then bigger off on mat leave again.
I won't be able to save to have another baby doing what I will be, and by the time I've paid my owed tax I'm on zero, so my question is what the hell can I do to earn money?!? (Not mobile hairdressing)
I'm a quick learner, I'm feeling pretty desperate

Would the salon owner be able to get someone else in to cover the hours that you are no-longer doing and reduce the rent that your paying?

Oh just another thought - what about specialising in personal wedding hair services? e.g you turn up on the Saturday morning make bride and bridesmaids hair look lovely - then get the rest of the week off save for the odd client meeting. I'm sure you could charge quite a bit for that.
