depression

This is my first post. I have spent the last 18 months battling cancer and have just reached a REAL low. I have been reading the posts and blogs recently and now feel the need to vent my frustration. I feel as if recently I have reached a dead end. I've been very positive up to now but feel lost at the moment.

It's been 2 months since my op to remove a Pleomorphic rhabdomyosarcoma Grade III from my left thigh. I'm on day 4 of a 30 day radiotherapy session and I start physio in a fortnight.
I'm down to one crutch if I leave the house and can hobble around on my own inside, as long as something is close by to hang on to.

I was accepted yesterday for the Hestel and balans course here in holland which means healing/recovery and balance think the balance means balance back into your life. I am real pleased as there is no balance in my life at the moment i feel like i am on an emotional rollercoaster and am going though many fears i never had before.

into my 6 week of chemo and should be having my 3rd dose next week . i suffer from bouts of depression anyway . but i don't think what i'm feeling is , i think its self pity!
