Hello, I'm 18 years old and for the past 1-2 months I've been feeling weird. Let me give you some information. I've been diagnosed with hypothyroidism and I've been taking T4 pills since I was first diagnosed, up to now, I'm doing pretty well with it. I'm a computer enthusiast and a hardcore user, I play games for hours with breaks. I'm in a rather good physical condition, I work out and generally I'm pretty healthy. I feel a slight dizziness/lightheadedness while laying down, sitting down and starring at my computer monitor. As per writing this, I''m getting this feeling of dizziness, like I can't find my balance but it's just a feeling, it's not like I actually can't hold my balance. I don't feel nauseous but I get this feeling of being moved, sort of like vertigo but not exactly. I don't know. I'm kinda scared because I don't want to be malfunctioning, what should I do? Where should I go to seek help? Also, when laying down and when I move my legs, I feel like I'm moving way more than I should. Recently as per writing this, for the last 4-5 days I've been feeling upset in my stomach for no apparent reason, I have tendencies to vomit without actually eating anything. I've gone these 4 days eating very little and not being active. I've been drinking regular amounts of water tho.
