Lonliness is certainly something that affects many that are depressed. I know that it hits me at times. When I'm depressed, it's a conundrum...I want to be around people because I know it would make me feel better, but I don't want anyone to see me when I'm depressed...If someone is sending nasty texts to you, block them. I am of the belief that relationships are better understood in person anyway. With texts, email, etc. I never know if a person understands the nuances of language and communication that are intended (or not intended) to be conveyed. See if you can reconcile with your sister/aunt, but try to do so in person. Best wishes to you.
