I'm in a very similar situation. Most people cannot understand what some of us go through because they haven't lived it. In my own way I look to these forums to try to connect with people with similar problems in order to give support and understanding and receive some through communicating. The stress of a move is tremendous especially when being an older individual. When younger moving was exciting not so anymore for me, just super stressful which has brought me unbearable anxiety and depression. on top of the depression and anxiety I started having before I moved and for the same reason you mentioned to be closer to the little of family I have left. I am happy in one respect that I finally saw my sister after years and live a day's drive from her now.
Medications are complicated because when it comes to antidepressants, mood stabilizers and so on they are based on theory with no sound measurable evidence behind their claims which is often why people find them ineffective. I don't trust the psych medicines any longer and prefer to be off of them. I have been prescribed Prozac and Gaba Pentin this time and again I get no benefit and actually feel they're making me feel worse in my head with anxiety, depression and insomnia. I find some relief yet with an antianxiety medication that has been prescribed to me over many years and have come to find out it's a benzodiazepine Clonezepam which I am physiologically dependent on now daily and it took has lost some of its original effectiveness and I am in a very debilitating depression right now for so many reasons due to events over my lifetime that made me vulnerable and I own up to my own part in some of the bad outcomes that I live with now. I no longer belief anti-depressants are good for me or will help me so I am going to talk with the psychiatrist NP and request that she wean me off of them after giving them a try for a month or so. Cold turkey is not advisable and can lead to very serious outcomes. Well, I appreciate the interaction with you.

There are some different genres of relaxation breathing exercises and guided meditations online that I find certain ones help me pass bad moments with a slight bit of comfort for my anxiety flare ups. There's also healing frequency music in many forms on YouTube if you Google them in a search and you may find something that could help you get through desperate moments. I have been bed ridden with depression for a month or so but I am usually very active and I know that some walking or other exercise can help with depression and anxiety even if it's around the house just moving the body. Always wishing the best for us and relief and comfort somehow.
