Hi, I think I have symptoms of low testosterone. I have bipolar and am on medication for it but have been experiencing these symptoms for years before I found out. I've gained weight which is hard to shift, barely eating, low libido (can still get horny but very weak erections and sometimes not at all) I feel weak and fatigued and generally feel ''off''. Does this sound familiar to anyone experiencing this? I'm planning on ringing the doctor to get it checked out but am scared. I'm 20
