No libido from last 6 months. Normal?

My libido has been totally vanished, I used to get rock solid boner every time whenever I used to think about sex. I used to masturbate a lot, sometimes 2-3 times a day and once a day was regular. But from last 6 Months, I don't feel like doing it. I don't get sexual urges, no sexual desires. However I have recently gone through a lot of failure such as visa rejections, not being successful in what I am doing. I used to get anxiety attacks which used to made me suffer from severe headache, eye pain and being unconscious. Then I contacted a doctor he prescribed  me medicines and I was all fine then,  but this libido problem was persisting before this issue.Iam really fed up of this problem, i dont know why my libido has been gone. Is it permanent ? I don't get enough solid erection whenever I am with my gf in a room which m akes me unable to peneterate. However, I never had sex. Is this phase normal? I am less attracted to porn than ever, I do not get a boner even from porn.
