If you can sleep 12 hours a day, have good hormone levels and digest your food properly they you have 3 important conditions to help you make it through this. The rest is you putting aside certain things that you once took for granted. You need to start with the basics, sleep, diet and general well being. Sex is not important right now. Hopefully you are taking medications under medical supervision and not experimenting with your body. Don’t take unnecessary risks because you might be panicking or over obsessing about your health. Get your mind clear it can work against you and lead you to make mistakes that you can’t undo. If your not already you need to speak with someone, family members, people you trust or a therapist. You would be better explaining all this to an adult and not someone who is 18, with little life experience and only sees the same as you. Explain your thinking behind taking all these drugs, it may seem normal to you but to someone else it could sound reckless.
From there you plan for the future, accept that the life you wanted has been put on hold for now. Believe you’ll get it back someday, you’re still very young. Refuse to give up your life to a drug company.
