Not eating, for anyone, is a cause of stress, drowsiness, mental and physical fatigue. Anyone who's been in class and skipped meals that day knows that the mental won't work when hungry. First I'd start by fulfilling this essential need. Try eating things you like, fruits and vegetables, or soup like harry4 suggests.
Second, you seem to be a bit like me. When I should worry about
the hard events going on in my life, I don't. And I end up worrying more about
going crazy or getting ill, but the real cause might just be the fact that you lost your job and can't see how to relieve your financial burden. Being jobless and having bills to pay is in the top 10 list of the most stressful things that can happen to someone in north america. The tension has to be relieved one way or another. Some get to drinking, others will live their emotions through anxiety.
And last, medication isn't meant to make people go crazy, or sick. It's meant to help like crutches. Just like a broken leg, you can avoid the hospital and wait until it heals, it will eventually but might take more time. Meds are not poison, they're meant to help when you need them. It's up to you. For me I was reluctant to ask a doctor, I've waited a long time before I talked about
it, but it helped me a lot to progress really fast. In the past I've also used pills sold in health food store. They can also be good for some people, for certain degrees of anxiety. Some of the clerks in those store are very well informed about
anxiety and natural treatments to it. But usually these treatments give relief in long term, rather than instantly with doc meds.
It's up to you to know what you need, or mayber seek help from a therapist, or a perhaps someone you know personnaly could help you meet a friend who's a therapist, and with whom you could talk to briefly, without impossible fees...
Hang in there, it goes away
