Anxiety mixed with depression issues WHAT TO DO ?

my best friend died a few months ago and i still can't seem to
get myself back into life.
YES work is going okay , I'm keeping my mind busy there but then i come home and veg out in front of the computer, I know this is not healthy mentally or physically .

I don't take legal or illegal drugs, feel negative about addictive chemicals.

What do you suggest to lighten the load of a high anxiety fellow human ?
Thank you

Congratulations that you've made it this far.
I've experienced some similar feelings and it was so painful my body that I didn't get out of bed for many months.
Once I felt well enough to crawl out of bed I devised a plan, went visiting old friends and family members for about a month to get that voodoo monkey off my back.
Getting involved in other people's lives and being useful to them helped me to become strong.
You will get better

A really good answer would actually take a back and forth chat. You need to take inventory of yourself, which is difficult to do when you're feeling crappy.
Think back to when you had hobbies and interests that occupied your time and see if you could see yourself picking those up again, instead of vegging.
Look around work for decent people you might want to hang with after work from time to time so you can have some kind of social life.
Consider classes in something you've wanted to learn or maybe even check out some churches as a way to meet people if those kind of people don't totally turn you off.
Just brainstorming...hope something helps. Been there.
Work out! walks, yoga, or the gym. If that doesn't work for you read , walk your pet, burn some incense. I went through a very high anxiety point in my life and I went to a counselor too. I never thought it would help, but it did. Utilize your friends and family if possible. I wish you luck
I have read tons of metaphysical books so my take on death is that it's better over there and your friend is feeling great (and wants you to feel better, too). If you can catch psychic Sylvia Browne on Wednesdays on the Montel Williams show it will either help comfort your loss or be a hilarious waste of time. Try it and see. Get out in nature if possible instead of in front of the computer. Focus on somebody else so you can't dwell in your own feelings (help someone move, renovate, watch their kids, visit your family if they aren't depressing dysfunctional dorks).
You need exercise and uplifting diversion. Life has these times of contemplation for a reason. If you can't pull yourself out, don't be shy about talking to a shrink for a couple of months.
For emotional release, perhaps you can take someone to an amusement park and yell your head off on the roller coaster. It's an appropriate place to practice primal scream therapy. Best of luck.
Oh, My mother had good luck with going to a berevement group after my father died. It's a safe option if you want to commiserate with others who are trying to process a loss.
