Agoraphobia please read need advice

So this is probably my 20th discussion on here but whatever lol.

Here is my situation I have been struggling with air hunger and shortness of breath all of this year and during this distressing year I have lost my job because I think I'm dying I have been to the hospital family doctor specialist etc in a attempt to find out what is causing me to be short of breath they cannot find anything they attribute it to anxiety.

While this was going on I stopped doing everything no longer work out short of breath no longer have a job let my car insurance lapse my tag lapse and now my car isn't running I let the battery die.

I've been riding places with my younger brother and he has been my support system during these tough times.

Tomorrow he leaves to go to college and live in a dorm and I live at home with my mom and she works all the time so now I'm here by myself facing death on daily basis and I do not know what to do to overcome this my car isn't running the battery is dead from sitting so long I just don't know what to do now..

Do you ever feel overwhelming fear that will stop you from doing things? KERI

Yes a fear that I will go somewhere or do something and I will die in the process so I stay home so I will die at home if something goes wrong

I just know for certain if I drive by myself I will have a intense panic attacks and I fear I will faint behind the wheel

I'm terrified of going into grocery stores right now

Me too what happens to you phsyically when u go into a grocery store or even think about going to the grocery store how is your activity level do you exercise it does agoraphobia get in the way of that

You need to go to your doctor and ask for help !! Tell your mum how your feeling so she support you ! You can over come this !!! Please please go and get help 

I start shaking and sweating and sometimes I have to leave the store....what about you?

Shortness of breath and fear I'll faint and die in front of everyone
