You sound like you’re struggling a lot at the moment. Depression and anxiety can be huge hurdles to contend with daily...I feel for you. Loneliness is a very painful feeling as well...
It’s entirely up to you if you feel comfortable doing this or, but I’ll mention it anyway (just in case it helps). Just so it’s personalised, I would perhaps suggest giving the BeyondBlue helpline a call on 1300 22 4636 to speak to one of their counsellor. S/he would be able to direct you to local services, groups, etc.
I hope this helps a little :)
