Hi lilstar, I think anni's suggestions are excellent ones.
Something I have noticed about myself: if I 'have' to reach out, even leave a message etc, I also feel lousy and second-guess myself, and end up with a lot of self-blame, or coming to the same conclusions you have mentioned- I feel very much a burden.
On the other hand, if I 'connect' and just 'ask' or talk and get feedback, it's not as Big a Deal and oddly enough I feel stronger and proud I had the courage to do so, I feel better about myself.
Being realistic, people (even T's) have lots going on, and might not even know how or what to respond. Yes, you 'may' be a burden etc,- (I very much doubt it, to your T), but far more likely is that not being able to connect and have feedback that it's ok to ask, the self-blame and negative thoughts are coming from within yourself and snowballing and telling you- 'confirming' if you will- your fears and confusion; it is very less likely that your fears are all founded. It's those emotions making it worse. You are just struggling- write it out, write here, google, etc.
Hope this makes sense.
-Hugs,
Meg
