I've been sick for 3 months and I need advice in building myself up again.

I was getting panic attacks for 1.5 months and it turns out it was low blood sugar. During this I rarely left the house, I was unemployed apart from my freelance journalism job, had no money and just moved into a new apartment with my v patient boyfriend. The apartment has no natural light so it's very hard to wake up in the mornings. The panic attacks went but I was left with bad fatigue. I think it was down to lack of routine and natural light. I tried exercise dvds but I was so wrecked. Also I was on a budget so often had to eat what was there and combined it may not be totally nutritious. I do eat healthy but for example if I only have brown bread in the house or whole wheat pasta then just eating that isn't obviously a good idea. Then I thought I was getting back on track but felt a bit strange socially. Like visiting my boyfriends mother's place in the country I would feel dizzy and need fresh air a lot even though I was avoiding sugars. After eating food even really healthy food I feel sick and can't look people in the eye I get nervous and jumpy and can't socialise if there's food in my stomach. It's v v very weird!! I have no desire to try anti depressants as at the beginning of the summer I had a terrible reaction to SSRIs and medication never tends to suit me. So I went to the doctor yet again and was diagnosed with GERD and told it should clear in 10 days with medication. It's gotten rid of most of it but I feel dizzy and weird now in social situations, if the weather/room is hot, if someone is too close to me and if even my parents talk too loudly. I just have a general feeling unwellness. I want advice on exercise, and diet and perhaps herbal remedies. Also if you've experienced this and think it may be food allergies let me know. I've not had the best summer but I want to be healthy again to have fun. I'm not technically depressed, my mood is fine but this annoys me. Social situations are making me nervous as I'm afraid I'll feel sick if I go out. I think I need to get back into things gradually and any advice will help as I'm eager to get back working. I worked all my life and was never sick and totally have no interest in sympathy. I wanna have fun, travel, work and be the ambitious go getter I once was. I've been sick for 3 months and I need advice in building myself up again.
