Yes, you can have someone with you at the assessment, in fact, it may count against you if you do not, especially if you have problems with Going Out, Communicating or Mixing with Other People.
Whoever goes with you can provide their own letter of support if they are willing. it needs to be formatted as a letter, they need to explain their relationship to you and how often they see you, the difficulties they see you have with the PIP activities and lastly they need to attest to the validity of the information and sign it.
Take a copy to the assessment and ask the assessor to read it and include it in your file before they start the interview.
