Solo :( I would help you - I would be able to do it in a non judgemental way and I would not force you to give up anything you weren't ready to do. It is very sad that you don't want people to visit you etc. You are so incredibly lovely and you must be missing out on so much in RL - you need someone to help you heal the pain that you have been through x
Cat64 - PM me if you like rather than answer on here... but how much would you be prepared to pay for this kind of service. I have a few friends who I help out from time to time and they and other friends tell me I should start a business doing it and I've considered it from time to time - but I don't know that anyone would really pay much to have it done. I think there is (or used to be) another poster who does this too.
Glittershoes - I understand you :)
Loudlass - that's really sad. There are often underlying reasons why people hoard things - people who don't at all are lucky that they don't feel the need to or understand it. With the girls clothes - try calling the charity shops and explain to them how much clothing you have bagged up and be honest about the quality - surely one of them would come out to you? If not, how about freecycle? Keeping the cards is fine 
Poshbaggirl - it's easier to help others out because you aren't emotionally attached to the stuff :) It's not your 'blanket' that's dirty and smelly.
Lexi - although not as traumatic as other people's experiences, it is still - as you say, part of your makeup (excuse the pun). I have my own markers (similar to yours) and come from a family of 'it might come in handy'ers. Not can't get in the room hoarders or 'collectors' though and I'm not like that - so I think a lot of it is how you are brought up and you either go with it or rebel against it.
DoTheStrand - you are very lucky not to feel the need to hoard. I am sure many people are really envious of you - I would love to be that unattached to things. Have you looked at your mum's life to see why she might be a hoarder? There's usually a good reason for it.
Gremlin - would you pay for a service to help you do that?
Goodynuff - please don't answer if you don't want to... but what the hell living arrangement do you have that someone comes and checks your apartment??
I suppose I sit on the fence really. I do keep a lot of sentimental stuff but I don't hoard everyday stuff - newspapers/jam jars/computer manuals etc and find it hard to understand why anyone does - but I'd never sneer - because there's always a reason and it's usually very emotional.
