1) make sure you use reliable yet reversible contraception, because it would not be prudent to have children now, but you do want to preserve the fertility for later, when the dust clears

2) you need to have a work-up with a psychiatrist and start seeing a therapist. Your issues seem severe enough to make an appointment with a psychiatrist right away, bypassing the GP route (especially since you suspect bipolar and a GP would be likely to prescribe antidepressants alone, which could lead to horrible things happening)

3) put the idea of help groups on hold now and only see professionals whom you pay - hopefully, knowing that you are paying for professional services would help you actually report to appointments, rather than get too anxious to pick up the phone. Plus, you have severe issues so you need professional help.

4) you seem to be unable to work due to social anxiety. If you have worked in the past, you might qualify for disability, so you need to look into state disability for your state.
