The trick is to go out, even if you do not feel like it. Push through it. Just do not go looking for "love". You are breoken ATM and broken attracts broken. And you have enough broken in your life right now. Hiking does wonders for the soul. You are still veeeeeeeeeeeeery early in all of this and I assure you that all that you are feeling is perfectly normal. I can share my timeline with you if you want. In my case the breaking point when things started too look up was about 6 months from BD. And then it took another 6 months till I was in the region of mostly OK. Now, 3 years from BD, I am great. Occasionally I still get the blues, but that's on the order of once per 3 months or so, and I can shake it of within the hour.
