Hi there and welcome back! I'm so sorry to hear you lost your father. It can be very difficult to keep motivated when facing such a dramatic loss. As for having failed attempts at weight loss, you're in good company here! I've lost count how many times I've started and stopped!
To change your signature, click on 'User CP' on the left hand side of the the blue band above. Then look along the left hand side, you'll see 'Settings and Options' and under that your should see 'Edit Signature'.
As for vegeterian protein sources that do not include nuts or eggs....all varieties of beans, edamame, Greek yogurt and other dairy are all good vegeterain protein sources. You could always add whey protein to a smoothie to get in more protein as well.
