I'm in a similiar situation as yours so I may not have the best advice, but I hope you'll feel a little better knowing you're not alone and I'm sorry that you're having such a hard time.

I used to have bad hygeine (and some days I backslide), but it's a relatively easy way to start to make yourself feel better (there's nothing like a hot shower or bath). Could you buy yourself some nice shower gel or a new shampoo?

Do you live nearby your mom? If so or when she can visit would she be able to take you shopping? Get you some better fitting clothes?

I see someone else has mentioned taking a college class which is a good idea and something I'm working up to doing. If you can't get to school on the bus/too depressed/anxious to go, maybe you could take a class online? Check your local college's website/give admission a call.

I've also started going to NAMI peer meetings, you could check their website to see what's available in your area.It could be possible to find someone willing to give you a ride to meetings. You will meet people who know exactly how you feel and knowing you're not alone is a great thing!

Ignore the dog abuse crap and know you love your dog and play with him/her inside. I chase mine around the house and he loves it. Does your dog enjoy playing with toys?

I am so lucky to have neighbors who are nice, but I live in a small community where everyone knows everyone else and their entire families too. Even as nice as they are though I know they must think I'm weird and I worry that I embarass my parents. I'm so sorry yours are mean to you.

I hope any of this helps!
